I use those containers too. They are big enough to hold quite a bit of stuff and because they are clear you can always see what's inside. I do use Goo Gone and then wash with hot soapy water. One of the other recycle deals I do is use empty prescription bottles (the kind with the hard to get off tops) with a hole punched in the top to put my old needles in. The other day, I received a gift box that had an oval aluminum top and bottom so I kept them to use as mini trays for my current quilting do-dads. I use a Pandora jewelry box to carry pins back and forth to quilt class.
