Hello, I'm in a bit of a bind. I don't know all the tricks and trades of this profession and I'm stumped about how to get my fondant bow to stay on the side of my cake. The cake is covered in buttercream; the bow is 4" wide made with fondant that is 1/8" thick. I stuck a toothpick in the back thinking it would stick but it keeps falling forward. It's a bit heavy.
I have no idea how to make it stay. Can anyone help me?

I use Wilton candy melts for that.

I have used just icing to glue bows to crusting buttercream, but I don't know how heavy yours is or how high up you need to attach it. If it is big and heavy and you have to pin it high up, you may need to use a long bambo skewer.

You can also melt some chocolate chips in the microwave if you don't have any candy melts (you can buy these in Michaels or AC Moore). Melt in 20 second increments, stirring after each cycle until completely melted. Let it cool slightly (you don't want it too runny). Put some on the back of your decoration and hold it in place for about 15 seconds. It sets up very quickly.

melts are great for attaching all things fondant, however not sure it would work on your buttercream.

Thank you. I'll have to experiment I guess.
