I understand the "thrifty" gene, as I have it too. Save the largest ones. Pick up a plastic box with little compartments in a yard sale or thrift store, color match the bigger bits and file them, some day, you never know, you may need them. The little ones, I would save them till the spring in a little baggie, and then rotary cut them into shreds, and sprinkle them on shrubs or grass in the yard, the birds, and other animals will use them for nests. I save my thread cuts from my sewing machine, and spread them throughout my little woods. The neighbors think I am a bit off anyway, and I like to keep my image up.
