Pattern Details:

I used Lion Brand One Pound Yarn (worsted weight) for this tutorial. You can use any yarn and crochet hook appropriate for that weight yarn.

Note: For a beginning chain, I like to use a larger hook for hte chain, then switch to my regular hook size for the remainder of the project. In this example, I did the beginning chain in K/10.5 (6.5mm) crochet hook and switched to G/6 (4mm) crochet hook for remainder of the square.
