Crocheted Retro Squares

1.   Crochet 6 chain stitches.

2.   Make a ring by finishing with a slip stitch in the first chain stitch.

3.   Using the same colour yarn, cast 3 chain stitches and crochet 15 basic treble stitches into the ring. Finish the ring with a double crochet stitch in the first basic treble stitch.

4.   Change to a different colour yarn and cast 3 chain stitches (these 3 chain stitches form the first basic treble stitch). Then crochet a basic treble stitch into the same hole, so 2 basic treble stitches are formed in the same hole.

5.   Crochet a basic treble stitch into the next 2 holes and 2 basic treble stitches in the next and same hole. Finish the row with 3 chain stitches which form the corner. Repeat the following 4 times: 2 basic treble stitches into the same hole, 1 basic treble stitch, 2 basic treble stitches in the same hole, 3 chain stitches.

6.   Change to a different colour yarn. Start after a corner and cast 3 chain stitches, 1 basic treble stitch into the same hole as the chain stitches, 1 basic treble stitch into the next 4 holes and 2 basic treble stitches in the last hole.

7.   In the hole in the corner, crochet 2 basic treble stitches, 3 chain stitches and 2 basic treble stitches.

8.   Repeat the following for the round: 2 basic treble stitches, 4 x 1 basic treble stitches, 2 basic treble stitches, 2 basic treble stitches, 3 chain stitches, 2 basi treble stitches.

9.   Change to a different colour of yarn for the last round. Start after a corner with a double crochet stitch in each hole, a total of 12 times, to the next corner. In the corner crochet 3 double crochet stitches and continue like this for the rest of the round. Finish and secure the ends.
