Below are the materials I recommend for this project. You are more than welcome to go rogue, just be sure to check your gauge to manage sizing. Some links below are affiliate, meaning I'll make a small commission if you make a purchase, but this is at no cost to you.
This video shows stitch placement in back loops only (blo), first for the half double crochet (hdc) row, and then the slip stitch (sl st) row.
Review basic stitches + skills as needed.
I am quite human, so you may find a note or two here in the future. At the moment, this project has no known errors, or discontinued materials.
