I gave up on making tops, but I can't resist the fabric section! However, the prices usually send me away empty handed! I do have an amazing stash tho.... all of it is 100% cotton. I let my friends and coworkers know that I collect. They give me old shirts and dresses, etc. I also buy them cheap (a stain on the front doesn't scare me away!) for $.25-$1 (a dollar if it's really nice!!!)
I cut the buttons/zippers off and save them too. I cut the cloth along the seam and then roll it all up together. I discard the cuffs, the collars and the shoulder part that is at least 2 layers of fabric! It doesn't take up as much room with that stuff gone. I estimate I get 2 yards of perfectly good fabric this way.
