I thought I'd bring this thread back out rather than start a new one.
I have been working on a QAYG (quilt as you go). I purchased the steam a seam or whatever and it worked great except it was a little wider than I needed. So, after I finished that package I went back to WM for another package and thought I would get the cheaper version which is a little narrower and cheaper. Did I mention cheaper? I found the end and started using it. It was really really thin and hard to work with. I kept telling myself it's OK because it is cheaper and I can deal with it. One strip it tore off like scotch tape and I couldn't find my end. I got frustrated and just started pulling on it and thought I would just unwind a bunch because I would use it anyway. I had been using the plastic wrap on the outside! I hadn't even gotten in to the real stuff. No wonder it was so hard to work with. It did stick the bias tape to the back. Glad it didn't stick to my iron. BUT it was cheaper.
