I've made rugs for outside decks with doily patterns, LOL. It just comes out...bigger, LOL.
I've seen people make the hats for wall decorations with them, holiday patterns are neat, because they can be put outside and are nearly indestructable.
You do need a lot of bags though, but works up quickly, and that is a plus.
Considering the supplies are free, I'd say it's worth trying at least once.
