LOVE LOVE LOVE it! I just discovered this stuff and I've found all sorts of uses for it...
It works great for top-stitching the opening of a pillowcase closed (see both inside, lower edges?)
or for sewing a label onto something that is visible in the back
or when you have multi-colored fabric
or for top-stitching any other item closed (see the bottom center?)
A bit of a pain to work with but not too terrible. Plus its only a buck and change at Walmart :)
I'd love to hear of other uses you've found for it. I'd also love to hear that I'm not the only one who is just now discovering it!
