Oh I am sorry you are having trouble with the steam a seam II. I have used it and I kind of like some things about it being that one side is sticky and it stay's put until you press. I think it depends on where you bought it whether it is "fresh" or not, and that seems to make a big difference in the performance factor of the product.
I bought some at a quilt store (three sheet pack)and it worked great. So, when I saw some at a fabric discount warehouse, I bought it by the yard. Boy, I hate the last batch and am going to just toss the won't stick or paper won't come off stuff right out. Who needs all that extra hassle?
I am thinking that the first set was enclosed in plastic and kept the sticky from drying out. the other being by the yard and exposed, is just ruined.
