I made this with Red Heart Super Saver in Pink and used an H/5mm hook. The stitch I selected was the extended Double crochet stitch (edc). My piece came out 16 inches tall. If you use the dc stitch, it will be 13 inches high. This goes fast as it's only 24 squares x 24 squares. Of course you may use thread and a steel hook for a smaller unit.
This is a free pattern! I have also given you the link for a photo tutorial so you can learn the edc. It is not that difficult, very similar to a dc, but with an extra yarn over.
