I keep thread nets over all my threads. You can acquire them free at your local floral shop or if your grocery store has a floral shop within ask them if they would keep the nets for you. They are usually longer than you need but you can cut them in half for the shorter 1100yd spools and they're tall enough for those larger than life cones. Keeps the threads from unravelling when not in use. I have a drawer full of the nets when my older cotton thread nets bite the dust. They seem to unravel themselves in time. The flower nets do not even after cutting them.
