My wife recently went crazy for wet felting and bought a fair chunk of wool roving in a variety of colours.
Likely it will take a while to get through it all and I want to be sure that it is still usable for a while. Currently it is just being stored in sealed plastic bags. They do not appear to be air tight. She did try to vacuum seal the bags, which I am not sure is good or bad, but since they are not air tight it didn't take.
How can I store wool roving to maximize its shelf life in my home? I will assume there are considerations for temperature, humidity etc.
I live in Southern Ontario Canada. I get dry winters and humid summers. While the house is regulated, in general, every nook and cranny is not e.g. basement, closets etc.
