Here are a few Feedsack fabrics from my personal stash. I'll be adding more of them in the weeks to come. GetCrafty has a great page of info and links about Feedsacks. Here is a good quilt history page that talks about the use of Feedsacks in quilts. And this one by Jane Clark Stapel
Stephanie Feed sack is my all time favorite!!! I have a stack that I have rescued from various places but cant seem to bring myself to cut and use it. I am hopping over to the links you mentioned for ideas. You aren't selling yours,right???
