Free Pentagon Granny Square Pattern

The wonderful thing about granny patterns is that they stretch infinitely in continuous repeating rounds. You can make them as big, as colorful, as simple or as complex as you like. Whether you stick to a single colored yarn, or change textures and stitches as you go, they are always a project that flows. And the granny pentagon is no different in that respect.

The thing that makes this crochet pentagon a bit different to a square, triangle or even hexagon, is attaching them together. These aren’t shapes that easily slot together as they are, but you can still use them either as a singular shape or with some improvising in the joining.

What You’ll Need

To make my granny pentagons that you’ll see pictured here, I used DK yarn and a 3.5mm crochet hook. You can however use any yarn you like to produce your pentagons, just make sure you adjust the hook size to match. Although I’d advise side stepping novelty or chenille yarn for this one, it’s just not worth the extra both in my opinion!

Stitch Guide

If you are familiar with the classic granny square, you’ll be pleased to hear there are no new stitches involved in this pattern. It’s just the counting that’s a little different.

slst – slip stitch
ch – chain
dc – double crochet

Round 1

Make a chain (ch) of four stitches, then slip stitch (slst) into the first loop to join as a circle.

Chain 3 (ch3) as your first double crochet (dc), now working into the circle make two double crochets (dc x 2), then ch2, then make three double crochets (dc x 3), chain 2 again, then make 3 more sets of three double crochets, chain 2 and slip stitch into the top of the starting chain 3.

Tie off and snip off a tail of yarn, and remember to work that tail into your next round if you can. Don’t worry if you can forget, you can always hide the tails with a yarn needle or hook at the end if necessary.
