I purchase little plastic boxes in the jewelry craft department at WalMart for $1.47. They have little slide-in dividers in them (4, I think), each section holds about 6 bobbins, I keep bobbins by color in each section and have a section for empty bobbins for just in case. I keep a container for each of the two machines I use on a regular basis. They need very little storage space and are quite handy.
