Dritz Tailor's Ham is an excellent tool for those who need help with ironing curved seams. It is a firmly packed ham-shaped cushion with a contoured shape that helps to mold and shape fabric. It has a wool side to be used for woolens, synthetics, and any fabric needing a lower temperature on the iron. Use the cotton side for cottons, linens, and any fabric requiring a higher temperature on the iron.
