small molds

i have lots of beautiful soap molds--i filled 4 with grout mix--they came out very pretty --i wonder what to do with them--one is oval with a flower pattern, one is rectangular with a celtic pattern and one is rectangular with bees and a honey comb pattern--they are the size of a bar of soap -- right now they are unpainted and look very pretty-look like cement--all i can think is to put them in the garden and maybe paint some--
