Get all of the colors you need in one package when you buy the Sulky 3MM Puffy Foam Assortment. Sulky Puffy Foam gives a beautiful raised effect to embroidery which becomes 3D in appearance. Simply choose the color to match the thread being used, cut a piece of foam slightly larger than the design and place it on top of the fabric. Satiny stitches will cover up and cut the foam during the embroidery process, resulting in beautiful raised embroidery.
