does anyone have any suggestions on making seashells, i have the molds, but i don't want to make chocolate ones, they r to go on the tops of a 3 tier wedding cake, which instead of a fountain under it will have a bowl with goldfish,, i know weird.. i need to make this for this coming sat.

You can use the molds top make the shells out of fondant of gumpaste. Use dust to color the shells after they have dried. With fondant push into mold and trim the edges. Freeze for 5 mins or so and thern remove from molds as quickly as possible (before they start condensing and getting sticky.) Lay out on parchment to dry and then dust the colors on.

I have silcone molds that I use for fondant/gumpaste shells. You don't have to freeze them to get it out.

But if you are using the plastic (like candy molds) then make sure you dust them well and freeze them.
