Couple of things - I poured this mold using a marble slab as a base (very VERY flat) - cost me $2.28 at the local DIY store (floor tiles) -- the masters were destroyed trying to get them off the slab. Don't use Aileen's glue to put the masters to the base.

Next time, I'll try Elmer's white glue (or, maybe just double-stick tape).
