One of the things I love best about polymer clay is that it has a long shelf life. I don’t have to worry about it getting dry or hard before I’m ready for that to happen. The chemical make up of polymer clay prevents it from being user friendly with some other plastics. As an example, it will eat holes in Styrofoam. I personally love the plastic deli wrap sheets I purchased from my local grocery store butcher. I sometimes use a dedicated container for a project, using only deli sheets to separate colors all in the same box. Canes can be wrapped in plastic wrap or wax paper, and stored in a protected container. There are times when I’ve left some clay on my work area, but since I have a cat, I simply cover everything I’ve left out with a cloth. I keep a dedicated container for scrap clay, and I just drop it in without pressing together. I’ve gone through that later and separated into color families, and have come up with some awesome colors. Some clays have glitter in them, or fibers that are included to give them a stone look. I do not include those in my dedicated scrap contained. The fibers are not good if I want to use my scrap for caning. There is just no reason not to use uncured polymer clay in one way or another! There really are countless ways.
