I bought a couple of thread boxes from Joann's. They are tall enough to hold a spool of thread with a bobbin holder on top. There are a couple of different types of bobbin holders available; I got mine from Clotilde's. The bobbin holder has little notches on the side that you put the thread through so it doesn't unwind from the bobbin or the spool. I have used them for years very successfully. Hope this helps! Good luck.
