Head scarves. All you do is take a 24" squared piece of fabric, serge it, fold under the serge and top stitch and you have a huge selection of scarves for everyday.

I tend to use the solid colored ones more because they are easier to match. I just use whatever fabric I have left from a project (the thinner the better) and Im in scarf heaven.

Garment bags. I got some poly/cotton in white, and just capped the bags with whatever I had left. The zippers were donated, and I went a bit overboard with the piping, but hey, they work great.
