I did the same thing at my quilt retreat this past April. Someone had thrown away about 8 4-patch blocks with flannel and chennille!! Grabbed those babies. Plus, TONS of scraps that were no smaller than 3 inches square and larger! Plus lots of strips for make my "clothesline" basket or small rug! I had no problem rooting through the trashcan - yes I got some wierd looks but not after what everyone saw I had salvaged!
Here's a happy dance
for dumpster divers everywhere!
