Celtic Diamond Decoration
The Celtic Diamond Decoration is a quick and unique wall hanging that is made up of simple crochet stitches and a small amount of cotton yarn. This Celtic Knot is the same decorative knot that is in my most recent Celtic square pattern – the Celtic Afghan Square. Find the FREE pattern for that project here!

Celtic Afghan Square = Celtic Diamond Decoration
As I was working on the Celtic Afghan Square, I realized that the Celtic Knot would look great on its own as a decoration. So, I experimented with the pattern by doing the same stitches and process but using thinner cotton yarn. I LOVE the result and thought you would like it too! There are so many possibilities with the Celtic Diamond Decoration – you could add beads and gems and make each cord a different color. Plus, you could make it single-sided or double-sided depending on where you would like to hang it. I explain how to do both versions below! 🙂

For this purple version I used Size 3 cotton crochet thread – it came out a little smaller but everything else was the same to make it! This version also has a felt backing and beads (instead of a tassel) – I show you how to do it below.
Stitches and Techniques Used in the Celtic Diamond Decoration
Would you believe that most of the stitches used in this project are just the single crochet stitch??! So, even beginners could give this one a whirl. You’ll also need to know how to chain and slip stitch – that’s it! And since this pattern is the same as the first half of the Celtic Afghan Square, you can watch the video tutorial for that project to help you with this one! In that tutorial you’ll find it helpful to watch how to crochet the cords and then weave them together. If this is your first Celtic Knot project, you might want to first try a simpler one like my Killarney Hot Pad here or the Celtic Bracelet here. But I do provide an actual-size color-coded Celtic Knot diagram for both Right and Left handers to help you be successful. I think you’ll find that the knot weaving is not as difficult as it might seem.
Quick Video Tutorials!
I put together 2 short video tutorials to help with a few steps of this project. In this video here I show you how to join the Celtic Knot motifs to make the project double-sided. And in this video here I show you how to make a quick tassel. These videos are less than 5 minutes long and give you a little boost for those steps to help you be successful!

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

Join with sc (join with single crochet) = With slip knot on hook, insert hook into stitch, YO, draw up a loop, YO, pull through 2 loops on hook
Click here to watch a short video tutorial on this technique
Sc (single crochet) = Insert hook into stitch, YO, draw up a loop, YO, pull through 2 loops on hook
Back Loop Only = Insert hook only into the back loop at the top of the stitch
Click here to watch a short video tutorial of this technique
Join with sl st (join with slip stitch) = With slip knot on hk, insert hk into st; YO, pull through st and through lp on hk
Sl st (slip stitch) = Insert hook into stitch, YO, pull through stitch and loop on hook
YO = yarn over
Hk = hook
Ch = chain
Lp = loop
Sp = space
Sk = skip
Notes:
First 3 cords are crocheted (or 6 if you want to make a double-sided decoration)
Then the cords are woven into the Celtic Knot
Lastly the project is stiffened and a tassel (and/or beads) & hanger are added

Weave Knot:
You can watch the video tutorial for the Celtic Afghan Square to help you with weaving this knot:
Click here for the Right Hander video (it will be cued up to the spot the weaving starts)
Click here for the Left Hander video (it will be cued up to the spot the weaving starts)
Place color printout of Celtic Knot Diagram on corkboard (see supply list above for the FREE diagram)
There are 2 versions of the diagram – one for Right -Handers and one for Left-Handers – make sure to print out the correct one!
You may want to have an extra diagram printed out to put next to your work surface – It can help you with understanding how the knot design works especially when the diagram gets covered with the cords
We will be weaving the green path first, then the orange and then the white

Place beginning of Cord 2 on black square on green path and pin in place

Lay Cord 2 along the green path following the arrows making sure to correctly pass over the cord after all of the corner points

Place beginning of one of the Cord 1 on the black asterisk on the orange path

Lay Cord 1 along the orange path in the direction of the arrows making sure to correctly pass over and under the other cords

Place beginning of the other Cord 1 on the black circle on the white path

Lay this Cord 1 along the white path in the direction of the arrows making sure to correctly pass over and under the other cords – this cord with have several alternating over and under passes!

Pin across all places where cord ends begin and end
Remove knot from board and turn over so Wrong Side facing
With yarn needle and yarn tails on Wrong Side sew cord ends together and sew all corner “twists” in place (as shown in photo below)
**Quick Tip: (I’m always looking for ways to make my projects get done quicker – here are 2 tips for you)
You can tie all your yarn tails in a double-knot and cut them off about 1/2″ long – these will be fixed in place by the stiffener and won’t show on either version since the Wrong Sides will either be covered by the other motif or felt
You can also hot glue the corner twists and cords in place** 😉

Weave in all ends making sure they do not show on Right Side
Make Tassel:
Here’s a quick video tutorial of how I like to make this tassel:
Wrap yarn around hand 15-20 times
Tie yarn length in double-knot around top of yarn loops and trim bottom of lengths

Using needle thread yarn length through top loop and tie a double-knot on top (for hanger)
Optional: Slide beads on hanger
Assembly and Finishing of the Celtic Diamond Decoration:

Lay Celtic Knot motif Right Side down on aluminum foil on corkboard/blocking board
Paint Wrong Side with fabric stiffener making sure to not get any along edges as shown with white arrow in photo below – Stiffener should be applied inside the dashes of green loops that are along the outside edge (This is so the stitch loops can be sewn together)

Let dry completely
Repeat above with stiffener if would like stronger
Using hot glue gun attach tassel to bottom point of motif
Fold yarn length in half and tie in double-knot (for top hanger)
Hot glue to top point
Optional: Add beads if desired

To add beads make a few bead elements by stringing beads onto matching yarn or thread
I pass down through the top bead and then through all other beads and then go back through the next-to-last bead from the bottom
Glue bead elements on to Wrong Side of motif using photo as a guide (before glue on felt)
Optional Finishing:
Single-sided: You can hot glue on matching felt piece to the Wrong Side and trim around edges

Lay project on a piece of felt larger than project, hot glue it to the felt and then trim off the excess

Double-sided:
Hot glue on other Celtic Knot motif matching up all points

Then using yarn needle and long length of yarn, whipstitch both motifs together around entire edge inserting needle into loops between slip stitch edging and green ‘dashes’ of loops on Wrong Side (see white arrows in photo above)

White arrows point to what the stitching looks like
Here is a short video showing you how to do this:
Weave in ends
