Good Morning!! I am working on a cake for Wrestle Mania, for my husband. I am doing a buttercream transfer of the logo and want to put it on a board that will stand upright behind a stage. I was going to use a cardboard or foam presentation board but then realized, I have no clue how to get this to stay on??? Any advice?

A little more detail:
Going to have a vertical "Jumbotron" to display the Wrestle mania logo which is a Buttercream transfer. there will be a stage in front of that and then a ramp going down to a wrestling ring.

Thanks for any advice on how to make this work. Originally the logo was going to go on the ring so I guess at this point I could just print a logo to go on the board? Oh man I've already started the transfer...Still advice or ideas are welcome!!

Id highly suggest printing or fondant/gumpaste once the buttercream gets soft it will eventually fall

That was my thought once I realized what I was doing! Thanks for clarifying!! Oh goodness, I think I need more sleep!

Or you could do your transfer with royal icing and it will harden and stand up by itself.

If you had more time you could use "pastillage" which is an edible moldable icing. Its usually used for decoration which looks really good when it is applied.
