Hey bro, i use a place called the compleat sculpter, their prices are pretty good and they shipp quickly, i would say 25 pounds would do but to be on the safe side id order 50, then you would have enough for your next, i order 50 pounds at a time so im not sure what i use exactly, also im only casting 11x11 molds, some of the other guys could tell you for sure but this is a great place to deal with as far as service and prices, heres the link... <a href=\"http://www.sculpt.com/\" target=\"_blank\">http://www.sculpt.com/</a>
