Many people engage in some kind of projects that involve supplies. Knitting. Carpentry. Scrapbooking. Stained glass. Building Linux servers. Whatever.
When one has a hobby, somehow, through a magical process, the supplies for that hobby proliferate beyond reasonable bounds. Perhaps they breed in the closets, but in any case, one day (today, for instance) you take a look and realize you have far more supplies than you've ever used since taking up the hobby.
Get a paper grocery bag and fill it up with your excess craft cruft. Depending on the hobby and the stuff, give it to a school or charity or throw it back in a dumpster (which may be where you rescued it from in the first place).
