You've successfully created a double crochet square! Make a bunch of them until you get the hang of it, you'll get better over time. Now that you know...
This is my next beginner crochet square, following the single crochet one. I suggest you master single crochet before you continue with double. The main difference is the size because double crochet is about twice as long as single crochet. Good luck!
Step 1: Materials
For this project, you'll need medium/light colored yarn, crochet hook size H-J, tape measure/ruler, darning needle, and scissors.
