I fill about 20 bobbins at a time, then I place them in the small plastic pill bottles. They fit perfectly and I keep one right next to my machine--no mess, no fuss. I had one of those blue plastic circular bobbin things and never used it so I had to do something else.
The other night I wanted to sew on a different machine and was too lazy to get the cone thread holder, the serger was close--so I just put my cone of thread on one of the thread spindles on the serger--worked perfectly!
