I have 6 of these -

4 of them hold my embroidery thread and the other two hold my sewing thread. I love them because of the extra long spool pins, I can double or even triple up my small Madeira spools on one pin, or remove a pin to store a large cone. I keep bobbins on the pins with the spool of thread they're wound from.
