I second parnell. Linen cloth makes a very nice backing, and is very quick and easy to apply as well as pretty safe, as long as you don't go too heavy in draw weight. Stay 55# and under to be safe. You have to make sure it is 100% linen though. The other stuff will stretch and brake. I buy my stuff at Joann Fabrics. About 15 bucks a yard or so, but 2 yards will make maybe 10 - 15 bows or more, probably more. One thing that has to be stressed that does not get mentioned too often is you have to find out which way the linen is stretchy and which way it is not. It will be a safer stronger and less sluggish backing if you do this. I think it just depends of the way it is made and the way the strands are woven together. It's easy to find out, just take you bit of linen and pull it length wise, then pull it width wise, the way it stretches least is the way you put on your bow. It is actually easier to see this when you have a good amount, like a couple yards, as the stretchy way will stretch alot and the non-stretchy way won't barely stretch at all.
