#bridgesmathart is almost here! Crystallographic Napkin Ring Series is the artwork Ellie Baker and I made for Bridges Eindhoven. It showcases our new software tools for making fabric designs that coordinate with bead crochet.

Crystallographic Napkin Ring Series by Ellie Baker and me. Fifteen cloth dinner napkins are folded and rolled into cones, then arranged like the petals of a flower. Each cone is bound by a bead crochet napkin ring with the same design that is on the napkin fabric. To make the rings easier to see, the napkins are folded to place a strip of the unprinted back side of each napkin under the ring. Each of the 15 napkin/ring pairs corresponds to a different wallpaper group (one of 17 possible symmetry structures of designs that repeat in two independent directions in a plane). The other two wallpaper groups are provably unattainable in bead crochet. Charles Wampler proposed the clever method for adding two more groups to our earlier 13-group bead crochet theorem. Spoonflower printed and sewed the napkins from graphics files we generated.
