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. πŸ™‚

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! πŸ™‚ 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 β€œflipping” 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)

Supplies for the celtic crochet square including 3 skeins of yarn, crochet hook, needle and stitch markers

Special Stitches and Abbreviations:

Back bar of the Chain = When looking at the right side of a chain, you see many β€œV’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

Supplies to weave the celtic knot in the celtic crochet square - cords, printout of diagram, needle and pins

   Weaving Supplies with all 4 cords completed

**You can purchase an ad-free pattern PDF here in our Etsy shop**

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

Step 1 of weaving the Celtic Knot with 1st cord on diagram - diagonal loop

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)

step 2 of weaving the knot with second diagonal cord started to be laid down

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

Both diagonal cords completed on the weaving knot diagram - cords are in pink and blue

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

Cord 3 added to diagram - this cord makes a rectangle shape

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

First 3 cords woven for celtic knot in the celtic crochet square

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

Last cord started to be woven for the celtic knot

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

Step 2 of the last cord

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

Completed celtic knot shown with 4 different colored cords -  pink, blue, green and white

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

Close up of how to sew cord ends together with needle and yarn tails

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 β€œindent 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 β€œindents” around the knot between all loops; First indent is at number 1 just before section β€œA”

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 of the edging crocheted in green on a white wooden background

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 β€œ1” (see Diagram); hdc in each of next 3 sts; *β–  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; β–  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 β–  to β–  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 of the edging of the Celtic Crochet Square on a white wooden background

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)

Round 3 of the Celtic Crochet Square

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

Completed edging rounds on celtic square shown in white and green yarn

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

  1. 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.

    1. Thank you! Blue-greens are such pretty colors – I’m sure that would look great, too! πŸ™‚

  2. I’ve lately become obsessed with Celtic knotwork and your patterns are simply perfection to feed my obsession! Thank you!

  3. 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.

    1. What a great idea for the colors of each cord! I love it! Thank you for sharing πŸ™‚

  4. 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!!!

    1. Awww . . . this is great to hear! Thank you for your encouragement and kind words πŸ™‚

  5. This square is gorgeous. It would make a beautiful blanket, and I would use red, grey, black, and white.

    1. 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.

  6. I love the colors in the video tutorial. I’d make a cross-body bag from this beautiful square.

    1. 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. πŸ™‚

  7. This looks like a really fun pattern to try, and I love how it looks. There are endless possibilities for color combinations.

  8. 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

    1. Have fun trying it out – please let me know if you have any questions with it – I am happy to help πŸ™‚

  9. I absolutely love this pattern! I can imagine an entire afghan made of these beautiful squares!

  10. 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!

  11. Would this work on back pocket of jeans as a cover repair as got big hole from garden roses clinging on lol?

  12. 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!

  13. 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!).

    1. Yes, the CAL has a bunch of great squares in it! Lol – “fiber meditations” 🀣 That’s a great way to put it!

  14. I would change the outer “frames” to green, frame it and gift to my friend who lives far away from me now.

  15. Loving the look of this square, I will probably try it in jewel tone colors. Thank you for sharing another beautiful creation.
