When you are shopping the thrift stores, don't over look the bedding. I've found beautiful eyelets in the form of dust ruffles. I've found two next to new flat sheets. One, a DAn River king sheet, is one of my favorite summer dresses. One I've got in my stash is a pink rose on white. Not my normal choice of fabric, but who can argue with the equilivent of about 5 yard of crisp cotton for $2. Also got some great greens when I bought a duvet cover for about $2.50. (in a $5 bag!).
I'll pull some of them out and take photos soon.
