I have found that decorator fabrics will shrink. So you may want to prewash.
I have a friend who makes sleeping bags lined with waterproof fabric that are for the homeless. The heavier decorator fabrics are very durable and warm.
The local women's shelter might be glad to get totes for the adults or for the kids. They frequently land there with little to nothing and could use something to keep their few possessions in.
Maybe grocery tote bags?
