I use the Altoids tins as mini-sewing kits for my embroidery.
Also, I use the empty plastic Splenda "on-the-go" containers )that dispense the little Splenda tablets) to put my bent hand-quilting needles in. I just turn the dispenser upside down, press the dispensing button, and insert the needle in the dispensing hole. Release button, and viola...the needles are safe till it you dispose of the whole thing when it gets full!
