I’m not a crafter nor a jewelry maker, but I find a million things to put in the 3 sizes! I’m also not much of a DIY-er in making things, but I’m great at finding solutions to lots of problems around the house and use the bags for help. I have lots of tools and they need screws, nails, etc, to be kept in. also lots of jewelry items for fixing and changing locks, clasps, jump rings, etc., and they all need to be kept organized in the different size bags or I’d go crazy!
