I always use a Steel hook 7, and crochet thread size 10.
but you could use whichever one you like to make bigger or smaller earrings.
Chain 20, slip stitch in last chain to form ring.
Chain 1, sc 33 times in ring.
Change color, attach, sc in each stitch.
Change color, attach, sc in the next 11 stitches, 2sc in the next, sc in the next 7, 2sc in the next, sc to the end. Finish off.
I can make these in any football team colors. I friend said these ones are the Steeler's Colors.
