"Chizimi Shrinking Thread, large spool"
Chizimi Shrinking Thread is a polyester thread that sews just like regular thread until it is exposed to steam from your steam iron or a steamer. Upon steaming the Chizimi thread shrinks up to 30% creating a shirring effect and wonderful texture and gathers. Use Chizimi in your bobbin only, for less puckering, or use in both bobbin and as top thread for even more texture. While Chizimi will work with any fabric, the best results are obtained working with lightweight fabrics such as silk, chiffon, or organza. Large, sold per large 3,300 yard (3000 meters) spool.
