I am putting a satin ribbon around a buttercream wedding cake. Should I put the ribbon on at home or wait till I set up cake at event?

Bumping myself, someone please answer your opinion.
Thanks!

good question...if you're sure your tiers are perfectly level and there's no chance of any gaps, put the ribbon on before you get there...to be on the safe side, put it on after the cake is stacked.

I would put it on at the event...should give it plenty of time to crust a bit. you can back it with a strip of waxed paper cut to fit the ribbon is another way to help the icing from bleeding thru.

You could try ironing the ribbon and the wax paper together, the wax could melt slightly to adhere to the ribbon...

I have never done this but was first thing that came to my mind.

Hope this helps
