That is something I will have to try. Right now, I write directly on the bobbin with a sharpie. E for embroidery, C for cotton, P for polyester, etc. along with the thread # if there is one. I have the caddy that I use for bobbins only. I write the manufacture and type of thread on the bobbin on the outside of each storage area. Keeps them all organized. I use narrow tape to attach the end of the thread to the top of each bobbin. Maybe after tax time the reinforcements will go on my shopping list.
