When it comes to shrinking fabrics, not all materials can be shrunk in the washing machine or dryer. All-natural fibers like cotton and wool are sensitive to heat and may shrink when exposed to extreme temperatures. Synthetic fabrics like polyester usually need boiling water or high ironing temps for significant shrinking.
Pay attention to care labels on garments; some fabric blends shouldn’t be subjected to even moderate heat due to dye leaching, stretching of delicate fibers, or overall shape loss caused by intense temperature changes.
Choosing the right fabric for your garment is essential if you want successful shrinkage results!
