I have an outdoor weeding comming up in March and the design only uses clumps of mint leaves. In the picture they painted chocolate on the mint leaves, but my girl wants black and silver and we're talking 100's of leaves. I'm worried about tinting chocolate black and of course it melting. I ordered a mold and it came today and it only like 1/4' long Definately not going to work for me. Any tips would be greatly appreciated. Thanks so much!!
