Did this in the last hour of game. It’s a simple single crochet in the round with a few rows of front- and back-crochets to add the bottom edge or curve the sides a bit.

I did this as an experiment to see how this blue yarn would stripe out when crocheted. I didn’t like it; it spiraled and was ugly, despite me doing fairly well with handling the rounds.

I sized it for exactly one set of dice for my current D & D character.
