thread and bobbins and knots oh my!

Ever wonder how to keep full and partially filled bobins from unwinding in a container?  I think I have finally found a solution.  I went to Sally's( a place where they sell beauty shop supplies) and I was looking for a good file for my nails.  I noticed they sold these little thingies that they use when doing a pedicure. I immediately thought of the bobbin mess I had.  I bought a couple to see if I could put filled and partially filled bobbins in them.  These things work great.
Here are before and after photos of my bin for bobbins.
