I had a garage sale a week ago and had tons of fabric for sale and I did sell some and the other I took to a Goodwill. I did put in the craigslist that there was fabric for sale. It does help a little. I think that some people are using fabric out of their stash because of the cost of good fabric. I really have to need the fabric if I pay $11 - $13 a yard. This is just my personal opinion. I love to quilt but I have so much fabric that I know I can't use it all up even if I live to be 100 yo.
I would love to know how to put pictures on the QB of nice fabric for sale but I don't have the knowledge.
