Thread organization:

plastic bobbins, yes or no?
I use cardboard bobbins.. the plastic ones are nice, but I've gotten tons of the card board ones over the years and I don't want to rewind all the floss that's already done.

How do you organize your threads?
I've got 5 thread boxes with a few of each of the DMC colors.
Then I've got a few smaller boxes that hold my six strand sweets, week dye works, gentle arts sampler threads, dmc rayon, dmc metallics, silks, and krenik metallics.
