I have a large picnic basket that I store my threads and bobbins in. I put like colors of threads and bobbins in plastic Ziploc bags. My rule is never put anything sharp in there like scissors or pins. So I know it is safe to paw thru for the right color. I have snack size for specialty threads up to quart size for standard white and grey threads. It's handy when I need, green for instance to pull out all my green threads in one bag.
