Fold over elastic is a beautiful thing. You can make a skirt in under ten minutes with it. I tell no lies. The only problem with FOE is that it isn't always easy to find. I'm not 100% sure they don't sell it at JoAnn's. But I get mine at a fabric store down the street from my house which sells a ton of stuff bought at auction. It's a pretty cool place and I'm lucky to have it so close to me. BUT, still, it only comes in black and white. I did a really neat tutorial on how to dye here. But if you would prefer to just buy some over the internet here's a great link with elastics in multiple colors.
Fold over elastic is great for finishing off knits, lingerie and undergarments. But you can also use it to finish off thin cotton weave's like batiste for tops or a fine silk.
Anyway....on with the show!
