I've done a few cakes recently with fondant/gumpaste decorations, such as stars, sticking out of the cake on wires. The thing is that when I transport it, they tend to wobble a bit and cut the fondant a little. I'm always scared that they will slice down and fall. I'm wondering what others do about this... Do you assemble these at the location? I always take a picture of the completed cake before I leave so I need to place the wires in. Any suggestions or ideas??

Wires that aren't food-safe shouldn't be touching the cake. If you insert the wires into coffee stir sticks, the wires will be held into place and also won't be directly touching the cake.

I use the coffee stir straws they are light weight and small, I also take the #1 or #2 tip and insert icing into the straws untill the icing starts to come out other end of the straw, then insert the straw in the cake where aI need it. I let sit for at leist 10-15 min to let the frosting set before putting in the wires .

I made several cakes that like yours they started to pull away from the cake and making a mess. The above technic works pretty good for me Much Much better results

You can put them on the cake (in a food safe way, of course), take your picture, remove them, transport the cake, and put them back on again on site.

I like the coffee straw idea. I'm definitely going to try it next time. Thanks so much!!!
