Since I've already blogged about organizing my floss, I thought I'd show how I store it.
Here's a view inside the first bin. As you can see, I keep all my duplicates together and all the floss is in numerical order. This case has numbers 48 - 372.
I got the plastic bobbins from JoAnn's as well. I had been buying the small packages (20-28 per pkg) of bobbins for years then I finally broke down and bought 1,000 bobbins (only available online at joann.com).
