i've been looking for a reusable bag that can fold up and fit in my purse. i planned on starting a sewing adventure this summer when my class is over. (the last time i sewed was in 7th grade. i successful stitched my puppy pillow to the sleeve of my shirt.) if i fall into the same fate later this summer i've found my second choice. these envirosax bags are pretty and colorful and waterproof. how can you beat it for $8 bucks!
