Chenille Kraft polyester stems are the classic ‘pipe cleaner’ in a variety of shapes and sizes. Regular stems are 4mm thick and 12” long, bagged in 100 packs. Giants are a big 12mm wide and colossals are a thick 15mm wide, furry indeed. Bumps have an oscillating thickness that resembles a wave. Bend ‘em, twist ‘em, make shapes and have fun with this time honored craft staple.
