I started a T-shirt quilt and looked for some stabilizer. They sold me Heat 'n' Bond. I brought it home and didn't think it was right. So I went back to the store. Those ladies said, Yes that was what I needed. So I went back home. Then I saw on the liner paper that it should not be sewn so I took it back. It said I need the purple stuff, the light Heat 'n' Bond. I brought that home and have made about 15 squares with it. But I don't think that is right either. What will happen to that when I try to press seams?
