About the frosting containers. I have some very delicate laces that do not need to be folded, so I roll them around a bit of Batting and place them in the containers. I wouldn't do it for long periods for I do not know how the plastic would react on the lace. One is a good place for all my seam rippers that are so small I lose them frequently. Anxious to hear other hints for the use of the cans.
