A friend of mine worked in a men's tailoring shop; they custom-made suits. She just gave me a large box of "sample" swatches size 6 x 8 inches. Most are 100% wool, some are wool silk. Can they be used together ? I also don't want to do a rag seam quilt but not sure what to do. Do you use batting? Seems like it would be too heavy. My first thought was to make a cover for my dog's bed but these are pretty nice. Thanks for the suggestions you've all posted so far.
