I have a Norvise bobbin with 14 spools. I label the thread on the inside of the spool with a Sharpie so it doesn't rub off. (right VEE? lol) I couldn't justify getting the Norvise but I love the bobbin. When I first got my bobbin I hated it because it wasn't returning to my work. REE tried it and it was determined the return mechanism wasn't working right. Called Norm(he actually answered the phone), sent him my return spool and he returned a new one with an extra thread spool. Now I use my old bobbins to hold those extra things like wire, lead, etc.
