Now isn't really the time for yard and garage sales, but you can find really great deals there, lots cheaper than paying postage on free scraps, actually. If you have a quilt guild nearby you can join, often members bring in fabric and other items they no longer want and give them away to whomever wants them. I know we do in ours. You can also get a couple of yards of fabric in a large size 100% cotton woman's dress at Goodwill for about $4.
