I had a clear plastic bobbin holder like pictured here. Every time I reached for 1 bobbin, I got 10 other threads and rolling, unraveling bobbins all over the place. Also, the lid had no fastening closure. It was maddening. So I invented the Bobbin Bay. (See Nancy's Notions)No spinning, no tangling, no unraveling, no falling out. But if you don't get them now, they're going to be gone. I've discontinued making them. (Manufacturing problems)But my personal list of the next best bobbin holders are this: Extra Large Bobbin Box (Clotilde), Bobbin Saver (comes in various colours which is nice) then it's all downhill from there. Bobbin Buddies are just some other small pieces to get lost and/or in the way, imho.
