Crochet Granny Square pattern: circle in a square

Circle In a Square

Hello! It is time for another crochet pattern, and this time I am sharing a simple granny circle in a square.

Yarn and hook needed

I will be using Stylecraft Special DK and a 5mm crochet hook. You can use any yarn weight, just keep to the same weight throughout and use the relevant hook. I have found over many years of crochet that my work is neatest using a 5mm hook with DK yarn. However, for some DK the label recommends a 4mm hook, although I have also had success with a 6mm hook. Therefore, you need to try and find what is best for you, and for the yarn you are using. You can do this by making a test swatch before you start your project. It isn’t important if you are using this pattern to make a blanket, but if you were going to make a sweater or a poncho, then you would need to know the size of your finished squares.

The Circle Pattern

Round 1: chain 6 and join with a slip stitch to make a ring

Round 2: chain 3 (=1 treble crochet + 1 chain) then make 1 treble + 1 chain into the ring, repeat ‘1 treble + 1 chain’ ten times and join with a slip stitch to the first chain/treble. You should have 11 trebles + the first chain/treble, each with 1 chain space between. Bind off.

Round 3: join new colour into any chain space. Chain 2 and 1 treble into same chain space then chain 2 (=2 treble + 2 chain), 2 treble into next chain space + 2 chain, repeat 2 treble + 2 chain for all remaining chain spaces and join with a slip stitch to first chain/treble. You should have 11 groups of 2 trebles + the first chain/1 treble, each with 2 chain space between. Bind off.

Round 4: join new colour to any chain space. Chain 2 and 2 treble into same chain space, then chain 1 (=3 treble + 1 chain), 3 treble + 1 chain in next chain space and then into all of the remaining chain spaces, then slip stitch to join to first chain/treble. You should have 11 groups of 3 trebles + the first chain/2 treble, each with 1 chain space between. Bind off.

The Square Pattern

That completes the circle, next make we make it square by adding corners.

Round 5: join new colour to any chain space. Chain 2 + 2 half trebles + 1 chain into same chain space, 3 half trebles in next chain space + 1 chain, 3 treble + 3 chain + 3 treble + 1 chain into next space to make the corner, 3 half trebles + 1 chain into next chain space, 3 half trebles + 1 chain into next space, then make the next corner with 3 treble + 3 chain + 3 treble + 1 chain (corner group) into the next chain space … 3 half trebles + 1 chain into next chain space, 3 half trebles + 1 chain into next chain space, corner group into next chain space, etc, until you complete the round and then join with a slip stitch to first chain/treble. Bind off and weave in all ends.

The circle is now a square

That is your complete square, although you can add extra rounds to make a bigger square if you wish. You would not need to use half treble crochet along the sides for the optional extra rounds, just make groups of trebles with a chain inbetween.
