Celtic Crochet Square
The Celtic Crochet Square is Block 9 in the 2024 Moogly CAL! Thank you Tamara Kelly of the mooglyblog.com for the invitation to participate again this year! The Celtic Crochet Square is made with basic crochet stitches and Caron One Pound yarn. Thank you to Yarnspirations for providing the yarn for this project!

The Celtic Knot in the Celtic Crochet Square
If you’ve participated in the Moogly CAL before than you know that I have designed 3 other Celtic Knot crochet squares in 2021 (The Celtic Knot Square), 2022 (The Celtic Woven Square) and 2023 (The Celtic Blanket Square) – This one is similar to last year’s square as far as how complicated it is but not to worry! If you have made the other three, then you will do just fine. Plus, I have made a step-by-step video tutorial (click here to watch the tutorial) to help you with each step of this project including making the cords, weaving the cords together and edging the knot. If this is your first attempt at a Celtic Knot square design of mine, then I recommend first trying the Celtic Knot Square from 2021 here to get the hang of how these work. 🙂
Celtic Knot Diagrams – for Righties AND Lefties!
The Celtic Knot Diagrams for this Celtic Crochet Square are available in Right-Hand AND Left-Hand versions! 🙂 There are not many differences between the 2 types of diagrams but since Left-Handers crochet in the opposite direction of Right-Handers, this can make following diagrams a little tricky. So, now you do not need to try to reverse the diagram in your head and get all confused – I’ve done the “flipping” for you. I hope this helps everyone be successful with weaving the knot. You’ll see a place to download the diagram in the supply list below.
Skill Level: Easy (Crochet); Intermediate (Knot Weaving)
(All of the stitches used in this square are basic crochet stitches. The knot weaving is not complicated but has several pieces that may be more challenging for you if this is your first time weaving a Celtic Knot – You could also try the Killarney Hot Pad first to practice a very simple Celtic Knot)
Measurements:
Celtic Knot center = 7 1/2″ x 7 1/2″
Completed square = 12″ x 12″
Gauge:
14 hdc = 1 inch (Make sure to check your cord measurements with the measurements for each cord given in the pattern)

Special Stitches and Abbreviations:
Back bar of the Chain = When looking at the right side of a chain, you see many “V’s” and the chain looks like a braid. Turn the chain over and you see a series of bumps – it is in these bumps that you will work across the chain to produce a cord with even edges along both sides

Notes:
First 4 cords are crocheted – 2 for the long diagonal loops & 2 for the square-like loops
Then these cords are woven into the Celtic Knot with the help of a printable diagram
Lastly crochet stitches are worked into the outer edge of the knot to turn the design into a larger square shape

Weaving the Knot for the Celtic Crochet Square:
1. Print out Celtic Knot diagram – (Find diagram links in supply list above)
(This pattern comes with 2 versions of the Celtic Knot Diagram – one for Right-Handers and one for Left-Handers – make sure to print out and use the one that goes with your dominant hand (Left-Handers crochet in the opposite direction of Right-Handers so their cords will look almost the same but will curve in opposite directions so I created a diagram that accommodates this and helps Left-Handers weave the knot without confusion 😊)
2. Pin knot diagram to corkboard
3. Make sure Right Side of all cords are facing – Notice where cord ends will meet for each cord on diagram – at asterisk, square, circle and triangle

5. Lay beginning of Cord 1 (Dark pink cord in my photos) along Pink path lining up cord end with asterisk and pin in place – Photo 1
6. Follow arrow along Pink path and continue placing cord in correct position according to the diagram – pin cord so it is lined up with path
7. End of Cord1 should meet up with beginning of Cord 1 and will eventually be hidden under Cord 4 (white path)

8. Lay beginning of Cord 2 (Dark blue cord in my photos) along blue path lining up cord end with square and pin in place – Photo 2
9. Follow arrow on blue path and continue placing this cord in correct position making sure to pass over or under Cord 1 according to the diagram

10. End of Cord 2 should meet up with beginning of Cord 2 and will be eventually hidden under Cord 3 (green path) –Photo 3

11. Lay beginning of Cord 3 (Green cord in my photos) along green path lining up cord end with circle and pin in place – Photo 4
12. Follow arrow on green path and continue placing this cord in correct position making sure to pass over and under according to the diagram – Photo 4

13. End of Cord 3 should meet up with beginning of Cord 3 and should be hidden under Cord 2 (blue path) – Photo 5

14. Lay beginning of Cord 4 (White cord in my photos) along the white path linking up cord with triangle and pin in place – Photo 6

15. Follow arrow on white path and continue placing this cord in correct position making sure to pass over and under all cords according to the diagram –Photos 6 & 7

16. End of Cord 4 should meet up with beginning of Cord 4 and should be hidden under Cord 1 (pink path) – Photo 8
17. Pin across where cord ends meet and remove all other pins. Remove knot from corkboard

18. Using yarn needle and yarn tails sew together cord ends making sure that stitching does not show on the Right Side – Photo 9
Optional: You can sew all crossings at this point or wait until square edging is completed – having some movement in the knot loops can be helpful when adding the edging so I recommend waiting 😊
Adding the Edging to the Celtic Knot:
Please refer to the Celtic Knot Diagram for help with the edging placement
** Tip to getting the right number of sts: As I approached each “indent section”, I looked ahead to the next indent section and made note of where the next bunch of sts would go; I counted back from the next cord cross the number of sts that I was planning to make next; I started my next batch of sts in the st I counted back to **
For Round 1 you will work in all of the “indents” around the knot between all loops; First indent is at number 1 just before section “A”
You can use stitch markers to help you keep track of the placement of the corners – this tip will be marked with blue highlight

Round 1:
You will be working in the loop behind the sl st edging of all the cords
(If you would like to make this round more secure, you can work in 2 loops on the back of the cords below the sl st edging)
Mark each ch-1 sp with a stitch marker to help you find it for the next round
With Pink (Lighter Pink – same color as cord edging) join with hdc in st 4 sts away from where cords meet at “1” (see Diagram); hdc in each of next 3 sts; *■ dc at next cord cross (1); sc in each of next 5 sts (on Section A); dc at next cord cross (2); sc in each of next 5 sts (on Section B); dc at next cord cross (3); hdc in each of next 4 sts (on Section C); dc in next st; (tr, ch 1, dc) in next st – Corner; dc in next st; ■ hdc in each of next 4 sts *;
(You will be repeating the same stitches that you completed for the first side of the square along all other sides)
Repeat from * to * 2 more times;Repeat ■ to ■ 1 time; join with sl st to 1st st of round. (25 sts on each side with a ch-1 sp at each corner)

Round 2:
Ch 2, * hdc in each st across up to tr at corner (this tr will be the stitch right before the ch-1 marked with a stitch marker); 2 hdc in tr; (dc, ch 1, dc) in next ch-1 sp; 2 hdc in next dc; *; Repeat * to * around; hdc in last st of round; join with sl st to 1st st; Fasten off. (29 sts along each side and a ch-1 sp at each corner)

Completed Round 3 of knot edging
Round 3:
With Cape Cod Bluejoin with hdc in any ch-1 sp; (ch 1, hdc) in same sp; working in the back loop only (and can work in an additional loop on back of sts to make more secure as did in Round 1), (hdc in each st across; [hdc, ch 1, hdc] in next ch-1 sp) around; join with sl st to 1st hdc of round. (31 hdcs along each side and a ch-1 sp at each corner)
**You may need to work shorter or taller stitches than what is written here due to your tension, hook size and yarn thickness to achieve a 12” square – take time to experiment with which stitches will work best for your square and help you get the size you want. Here are the stitches in height order starting with shortest: Sl st – sc – hdc – dc – tr – dtr

Round 4:
Ch 2, (hdc, ch 1, hdc) in next ch-1 sp; (hdc in each st across side; [hdc, ch 1, hdc] in next ch-1 sp) 3 times; hdc in each st across last side; sl st to top of starting ch-2.
(33 hdcs along each side with a ch-1 sp at each corner)
Round 5:
Repeat Round 4. Fasten off Cape Cod Blue. (35 hdcs along each side with a ch-1 sp at each corner)
Round 6:
With Rose (Darker Pink) join with sc in any ch-1 sp; (ch 1, sc) in same sp; (sc in each st across; [sc, ch 1, sc] in next ch-1 sp) 3 times; sc in each st across last side; join with sl st to 1st sc. Fasten off.
(37 hdcs along each side with a ch-1 sp at each corner)
Finishing of the Celtic Crochet Square:
Weave in all ends on Wrong Side of square – Sew more of knot cords together at crossings to secure
Blocking:
Wet square with cold water so soaked through
Press out excess water with a clean towel
Lay out square on dry towel and flat surface pulling out spaces and stitches so lay flat and evenly;
Optional: Place corkboard under towel and pin square taut at corners and along sides to the 12” measurement
Let dry completely

I really like your website and all of your pretty designs with the Celtic knots, I love making Celtic knots.
Usually, I don’t put a border around my Celtic knots I use them as potholders, but just to put stuff on and my friends like them so I make a bunch of them. I tried this one with the border and that first round of the border is so painful to me. I can’t actually make another one. Haha, the directions were great but mine came out a little lopsided, but it still looks good. I used black and white cotton yarn so I’m just gonna use it like I use the other ones that I’ve made without borders. I’m seriously considering doing a solid half double crochet back piece so that I don’t have to do all those ends. 😸
Thank you!
YAY! I won the Give away. TY for the beautiful pattern.
You are welcome! 🙂
It’s intriguing to make the Celtic square. Because of the Irish connection and my home decor, I’d make coloring similar to what’s in the direction but use a deep and a medium blue-green. I’d eliminate the pink. The directions look incredibly specific and helpful. Congrats on your designing and writing skills.
Thank you! Blue-greens are such pretty colors – I’m sure that would look great, too! 🙂
This is really cute!
🙂
I’ve lately become obsessed with Celtic knotwork and your patterns are simply perfection to feed my obsession! Thank you!
Sounds fun! Hope you enjoy making the patterns 🙂
Beautiful! Love the colors. I’ve never made anything like this, but think I’ll try.
Thank you! I hope you have fun trying it 🙂
I love the look of this square. If I were to do this (after finishing a few other WIPs that I have) I would make each cord the color of my family’s birthstone. Red for my sister (July), Light Green for me (August), Blue for my brother and mom (September) and a Orange-Yellow color for my dad (November). Not sure what to do with the border colors yet, but I’m sure those colors would go great with the band colors.
What a great idea for the colors of each cord! I love it! Thank you for sharing 🙂
Your patterns are so beautiful and look so difficult, but they turn out to be quite doable because your instructions are so easy to follow…I love all of your patterns!!!
Awww . . . this is great to hear! Thank you for your encouragement and kind words 🙂
This square is gorgeous. It would make a beautiful blanket, and I would use red, grey, black, and white.
Great color combo idea! 🙂
This square is a joy to look at. I especially like the pinks and dark blue combination. For myself I think I would trim the cord in the dark blue as well just to make it pop a bit more. I also agree with a previous comment that an arrangement of these would make a beautiful afghan.
Edging the cords in dark blue is a good idea, too! Thank you for commenting 🙂
Oh, I was just admiring this square on Moogly site. It’s so pretty.
Thank you! 🙂
I love the colors in the video tutorial. I’d make a cross-body bag from this beautiful square.
Great idea! It might be best to make it with cotton yarn so it doesn’t stretch too much or line it with cotton fabric. 🙂
Beautiful square and love that there is such detailed instructions.
Thank you! 🙂
This is beautiful. I love the colors you chose.
Thank you! 🙂
This is a beautiful pattern.
🙂
This looks like a really fun pattern to try, and I love how it looks. There are endless possibilities for color combinations.
I agree! I think you’ll have fun with it 🙂
Love this square. It caught my eye right off the bat. I can see making this into a pillow and an afghan in earth tones, for my friend and neighbor. I can hardly wait to try the square for myself first to get the hang of the square. Thank you
Have fun trying it out – please let me know if you have any questions with it – I am happy to help 🙂
I absolutely love this pattern! I can imagine an entire afghan made of these beautiful squares!
That would look great! So glad to hear you love this pattern 🙂
I love this pattern and the colors! The pink cords with the blue edging is gorgeous! I love jewel tones and could see this in some beautiful fall colors of orange, gold, and maroon. Thank you for sharing your patterns and inspiration!
You are welcome! Those colors sound great together – I love fall colors, too 🙂
I love this! I think I would make my cords in medium teal, a muted green, sky blue and lavender
Oooo! Such a pretty color combination! 🙂
I love your patterns so much!!
Thank you for commenting! 🙂
Would this work on back pocket of jeans as a cover repair as got big hole from garden roses clinging on lol?
Oh no! Your poor jeans! This square is very big – the center knot is about 7 1/2″ x 7 1/2″ so it may work if you use much thinner yarn. Or you could try making the square in the Celtic Crossbody Bags that you can find in my Etsy Shop: https://celticknotcrochet.etsy.com/listing/1548346282/crochet-crossbody-bag-celtic-bag-crochet and https://celticknotcrochet.etsy.com/listing/1557740748/crochet-crossbody-bag-celtic-bag-celtic 🙂
Oh my goodness! I love this so much. You can do a ton of things with this! My niece was just asking for a celtic pillow to take to college! I think I know what Im going to do with this one! Thank you SOOOO much!
You are welcome! I love your pillow idea! 🙂
What a beautiful pattern! I think it would make a lovely blanket.
Thank you! 🙂
Oh, I love this!! Going to have to have a look at that CAL, as I know that squares for a blanket are a great stash burner! Your instructions are clear and concise, which makes it easy to follow (when I’m ready, I’ll purchase the PDF for this, though, as I find ads distracting – they get in the way of my fiber meditations!).
Yes, the CAL has a bunch of great squares in it! Lol – “fiber meditations” 🤣 That’s a great way to put it!
So lovely!
Thank you!
I would change the outer “frames” to green, frame it and gift to my friend who lives far away from me now.
What a special gift it will be! Love your green idea 🙂
Loving the look of this square, I will probably try it in jewel tone colors. Thank you for sharing another beautiful creation.
Loved making the bookmark from a prior post. Can hardly wait to do this one!
So glad you enjoyed making the bookmark! Have fun with this one 🙂
Thank you! Jewel tones would be very pretty 🙂
