Recomend a notion - Thread Storage
I ordered the doubled sided thread organizer from Connecting Threads, and I like it so much that I ordered another one this week. I use their thread (yes, I find it linty but oh well-I dust the machine and bobbin area often). The spools fit perfectly in the dividers. You flip it over to open the other side for additional spools. Had I understood that, I would have ordered it before now. I like to store my thread covered to keep the dust off and light out. It also has a handy carrying handle.
Please ~ recommend a notion you like, new or old.
