Buried in Yarn!

Help! I need a new way to organize my abundant supply of yarn. Yarn is so expensive, (for the good stuff), that when I find a bag of new yarn at a yard sale or Ebay, I have to buy it when it's available.
So, needless to say I have enough to last the rest of my life. I have tried numerous ways to organize it. Here are a few:

Put similar yarn together in plastic bags
Group the same colors in vintage suitcases
Decorative Baskets                                                                                                                                   I tried those vacumne seal bags that are "as seen on tv"

Nothing has been ideal. If you have any new creative ideas for me, I would love to hear them.
