I have lots of threads about placing royal icing decorations on buttercream, but what about gumpaste decorations on buttercream? As long as the gumpaste decorations are completely dry, is it okay to put them on?

I think if you leave gumpaste and/or fondant on buttercream for too long, it softens. So, if you have pieces that are not flat, they will lay flat after a while. I had that happen with some butterflies I made for a cake. I dried them for 2-3 days prior to needing them. When I got the cake to the site, they were laying flat on the buttercream.

Thanks, crl. So, I was thinking of transporting the gumpaste decorations in a separate container than the cake and putting them on at the party. It would probably be 1-1 1/2 hours before the cake was eaten. Do you think I'll have problems with a time-frame that short?

Another using gumpaste on b/c thread:

I think you might have problems. I think my cake sat for about the same time. It wasn't a big deal for me as the butterflies just laid flat instead of 3 dimensional. If your gumpaste pieces aren't going to be laying flat against the cake, I would wait as long as possible before you attache them.

they will absorb grease spots too
