I just got them and already used them a lot. I'm a newbie and thought these were just for the acetate.... but I use them for background too!!
These dies are great to use with the Sweet Shop kit and to be able to cut out extra acetate if I want.
I love having the outlines dies and have started adding them to my collection from your past kits. They help stretch the dies and make some different kinds of cards when I don't want to add shaker bits.
