|Since we are on a bobbin thread, here's what I do. I keep thread and matching bobbin in small plastic bags. I found the bags (2"x3" or thereabouts) at the checkout of one of the local stores. I think they were targeted toward jewlery makers. A couple spools of thread and a couple bobbins, all of the same color fit in the bag, making it really easy to find the match when I want to double needle, etc. I keep the bags in a couple decorative baskets near the sewing machine-- vaguely sorted by warm and cool colors.
