We've got over 30 colors available at the shop and in 3 different sizes, but to keep it simple online, we offer just the white in a large package. 170 meters (187 yards) of cotton sashiko thread in each hank.  Sashiko thread is specially twisted with 4-6 threads each twisted in a different way so that after stitching, when you block/wet your piece, the individual strands in the thread activate and combine in a way with each other and the fabric that regular cotton embroidery thread does not!
