I forgot to add, I use those price stickers for keeping track of block parts and sizes. Once I do my test block and start cutting pieces I put them in zipper baggies. Instead of writing on the baggie which can smear I use the price stickers. Plus when I start the next quilt I can just put a new sticker over the old one and keep using the same baggies. It really helps when some of the pieces are really close in size and hard to tell apart unless you measure every time.
