I designed and made this C2C crochet throw for my son several years ago as a birthday gift. The written instructions have not been tested, if you find any mistakes please contact me so that I can correct the file. Thank you!
Each square is approximately 12" when made with worsted weight yarn and a 5mm hook.
I worked two rows of single crochet around each block, adding two extra stitches at each corner in the second round. To connect them I followed the instructions on Repeat Crafter Me's page and then did two more rows of single crochet around the outer edge to give a more finished look.
