What is the thickness of the wood? If you are using 1/4", then try using 1/8" and stack cut more at once. As far as pricing, material is probably not much, but your time may be. If you want to get paid for the time you put into it, price it accordingly. A lot of ornament patterns suggest using 1/4" but I found that they sell just as good when made with 1/8" stock.
That's my two cents. (Dang it! I'm broke again.)
