Is it possible to make gumpaste seashells without a mold? If so, does anyone know how to? I have a luau themed cake that is due on Saturday.

You could use some real seashells and use them as kind of a mold. Just dust the shells with powdered sugar and form the gumpaste around the shell. Haven't tried it, but it might be worth a try if you have them on hand and don't want to buy real molds.

Thanks, I was thinking that too.
