I used the zig zag stitch on two pieces of paper where they wre joined, so it would look like real stitching, and it does! The only issue I have it maybe the black is not right for all projects. They make it in white, but I feel that would be too bright for my projects. I think if they made it in tan it would be more useful all around.
I bought these, thinking they'd be a cute addition to pages without having to actually pull out the sewing machine... boy, was I disappointed!! The quality is atrocious... they come off on everything, with just the slightest bit of pressure, and then they don't come off! I had to redo an entire page, not to mention having bits of rubon stuck on my hands for days... I had 2 of these and I think I may just have to throw them out, since they are basically unusable... :(
