Pros : random variety to try, challenges creativity
Cons : These are scraps, and as just a way to try out a quick sample, okay, but because they're left overs (read: edges where the dicro is weaker) the small chunks of pattern ended up as much frustrating as anything. Either the pappern was so small most of the slide is nothing or the pattern is so large you can't get a full single section to use. I'd much rather use a small hole punch and normal slide to make my own dots and not have them fad into obscurity half way though a piece that's not large enough to cover my 3/4" by 2" pendant b/c the angle the original person wanted to use.
Other Thoughts : This would work for some one wanting lots of no random looking but random seeming mismash. What works for solid colors doesn't play out with the patterns so much.
