Aunt Lydia’s Crochet Thread Classic 10 in Natural & Soft Mauve. You can make multiple Teeny Peenies from one ball of each.

If you want to make a circumcised Teeny Peen, skip the “back loop only” instructions, and use just one color. Also, skip the foreskin.

Weird sidenote, but I like to add one or two popcorn kernels to each testicle. Not for some weird reason lmao, it’s just the right size & adds a little heft to that end lol.
