Late the other night I finally started covering on my latest project!! The problem was for some reason it wasn't sticking like it should. Frustrated I finally gave up and went to bed. The next morning after a good night sleep and some breakfast I started back in - can anyone guess the problem - it's one of those things you turn your head and look around to make sure nobody was looking - I didn't peel the backing off! Works great without it.

How about forgetting to turn the iron on, same effect

I did that once but I was also using balsarite so it did stick. I figured it out pretty quiclkly though and only had to recover one side of the stabilizer that way.
