I have a suggestion for the storage of needles without danger. I store my needles in a circular mailer. You can get them in various lengths at the Post Office or the mailing supply section of Target, Wal-Mart, etc. The mailers are made of very hard compressed cardboard and don't crush easily (I have stepped on, sat on, dropped, mine with no problem). I have several mailers. One I keep the only the needles for my current project in and several others for storage. Inside the storage ones I have the "sets" of needles rubber banded together. And I have cut a piece of circular foam (left over from craft projects, appox. 1/2 inch thick) for both of the inside ends of all of my mailers to protect the tips of the needles. (Remember to cut the foam circle a little larger than the mailer so that it will stay in place once you put it inside the mailer.) I store my paint brushes in a mailer, too.
