Does anyone know where I can get a acorn silicone mold? I'm also looking for a tutorial for coloring autumn leaves and acorns. I'm not having any luck finding one.

Dont know about an acorn mold. Shouldn't be that hard to make with out one. But check with global if its made they probably have it. Also, check sculpty clay books they have alot of directions for this kind of stuff.

But to color fall gumpaste leaves. I like to start with a pale yellow gumpaste, make the leaves then shade with powdered colors, starting from the outside in. After coloring the leaves with the appropriate colors, i then hit the outside edges with brown. Layering several colors on at a time, will give you very realistic leaves.

I Googled *acorn impression molds* and then clicked on *images* - various photos showed up - as per this one.
