So I know putting wires into a cake is a no-no...what about the plastic stems of silk flowers? Can those be stuck into the cake (as long as there are no wires inside?) or is there a better way to attach them? Doing a buttercream icing.

TIA!

I don't think most silk flowers are made of food grade plastic. I don't know that anything bad would happen if you stuck them in but I don't imagine they're the cleanest thing around since they are unpackaged and probably get handled a whole bunch. I have a cake I'm doing in October that will have silk flowers and I'm going to treat them just as I would any other type, ie they'll be in flower spikes or straws so the cake is protected. Just my opinion!
