I ruler fold mine to avoid the bulk and the expense. One tip: measure the fabric BEFORE folding and immediately write down the amount. I use index cards cut in half. When your fabric is folded, staple the paper or index card onto the front. This way you will never have to guess (or unfold, measure and refold!) when selecting a fabric. BTW, if you wait to write down the amount until after folding you may have to remeasure...ask me how I know!
