"I prefer to use Sulky Stiffy because I only have to use one layer to stabilize most fabrics. For a project like my evening bag, Stiffy also gives the project the body it needs without using additional interfacings. Because Stiffy is so firm, I only need one layer when I am embroidering. I team it with Sulky Sticky when embroidering on T-shirts and sweatshirts. When i remove the stabilizers, my work is always smooth and unpuckered." -- Tom Kohl
