Origami patterns can be held by polyester fabric through
heat setting. Class attendees can bring their own 100% polyester fabric (or a poly t-shirt if you want an origami tee, but size up by a few sizes if so since it will shrink) but I will also provide a half yard of fabric in assorted colors. You can fold whatever you want so long as it's not too complicated, as fabric has a larger radius of curvature than paper. Corrugations work nicely. I have a heat gun to set the creases in the fabric permanently.
