About a year ago I made some fabric bowls using Timtex two-sided fusible interfacing for stability. I have a lot of Timtex left over and now I want to make more bowls and I don't have any directions for using the Timtex. I have to fuse it to a 4"square of material and then fuse that to another fabric piece but I don't remember how to keep the sticky side from sticking to the ironing surface (since it has two sticky sides). There is a clear plastic sheet that is rolled in with the Timtex. Can anyone help me? Thanks
