Are you a topologist who's keen to make an interesting mapping cylinder, a geometer who likes to see a beautiful surface spanning in space, a polyhedra worshipper, a knotter tyer who would love to expand your portfolio?  Maybe you are a crocheter in search of a novelty project, or a fan of Bathsheba Grossman, Charles Perry, and Brent Collins and would love to make small models of their work by yourself?  If you answered "yes" to any of those questions, or if you just want to crochet some interesting and beautiful mathematical surfaces, topological crochet is perfect for you!

Join artist Shiying Dong for an evening of math creativity.  With simple building blocks of chain stitches, single crochets, double crochets, and more, we will build topologically nontrivial, visually pleasing yarn sculptures.

Materials required:  Please have your own worsted weight yarn, a size 7 (4.5mm) crochet hook, split ring stitch markers (or small locking stitch markers), darning needle, and scissors or a yarn cutter.

Helpful tools:  Blocking pins, scrap yarn ball, and a cushion or foam board.

This is an online-only event; all registrants will be participating remotely.  The session will open just before the listed start time.  Occasional video recordings are made available for a fee at
