I stack mine. I have tall bookcases that I had extra shelves cut at home depot for so that the stacks of fabric aren't stacked too high and its easier to keep them organizied by color/design. Before I put in extra shelves I agree it was a pain to have to get fabric out of the middle or bottom of the stack. Now that the stacks aren't as tall, it's a breeze. I would not be able to store the same amount of fabric standing up or on boards. I also played with the folding until I came up with a fold that is the same depth of my shelves and saves space at the same time. I don't like my fabric in totes because I forget what I have and buy more. This has saved me so much money because I can work from my stash instead of increasing it with extra purchases.
