Celtic Knot Square

This Celtic Knot Square FREE pattern combines my love of Ireland and Celtic Knots with crochet!

I am excited to share this Celtic Knot Crochet pattern with you – Thank you Tamara Kelly of Moogly for inviting me to join in on the 2021 CAL fun! I have enjoyed seeing each square so far this year – it is amazing how you can make so many squares with the same yarn! This is square number 12 and I love how it turned out.

Stitches Used in this Celtic Knot Square

If this is your first Celtic Knot Crochet project – don’t worry. Most of the stitches used in this Celtic Knot Square are basic stitches and the knot weaving techniques are very easy especially if you download the accompanying color diagram found at the link listed with the supplies below. I also created a step-by-step video tutorial that you can watch here.

Celtic Knot Diagrams for both Right-Handers and Left-Handers!

To weave the Celtic Knot in this square there is a FREE printable diagram that will help you be successful. Now there is also a diagram for Left-Handers! πŸ™‚ Since Left-Handers crochet in the opposite direction of Right-Handers, their cords will be opposite and having a matching diagram will help. So, make sure to download and print the diagram that goes with your dominant hand. Download links are in the supply list.

Yarn Used in the Celtic Knot Square

I crocheted the square shown above with Red Heart’s With Love yarn – I have been crocheting with this yarn for several years but this is the first time I’ve used it for a Celtic design. I thought the Peacock color was so pretty and it caught my eye first. Then I chose the lighter blue (Iced Aqua) and the dark gray (Pewter) to go with it but of course, you can use whichever colors you like!

Supplies used for the Celtic Knot Square - yarn, hook, stitch markers

Yarn options: It is best to use a medium weight acrylic yarn if you want your square to come out the same size as mine – one skein is more than enough for one Celtic Knot Square. Start with picking a color for the cords of the knot center. I think it works best to pick another shade of the same color for the thin edging. Then you’ll want to decide on a color that helps the knot design really pop. As you can see by the photos, I decided to repeat the darker blue (Peacock) as part of the edging that turns the knot into an even square.
