I had the same concern a few months ago and started this thread:

I received a lot of good advice, but I think post #21 was the most helpful. I'm using her suggestion but with plastic totes and dessicant instead of bankers boxes. The totes I found are a bit larger than bankers boxes but not too much. Remember, whatever you use that fabric is very heavy.
