I have been saving those plastic containers that some salad greens come in. The lids snap into place, they are transparent, and the are a good size for all sorts of things. I put scraps of fusible webbing in one of mine, safety pins in another, etc. I just hate that I'm not able to recycle those in my area, so I try not to buy them. But if I do, they make good containers. Also, they nest together well and don't take up much room.
