What is the proper way to apply satin ribbon to a cake? I've never put ribbon on a cake and I'm thinking that if it's not applied correctly it going to show "greasy" spots.

There's a couple ways: I have put wax paper under the ribbon if it's wide enough, so that no grease gets on it from the BC, and I recently read a post where someone suggested soaking the ribbon in veg oil and letting it dry; that way it can't soak up anymore grease from the BC. I'm doing that method with 2 upcoming wedding cakes. If you're using a color besides black you'll want to get one shade lighter than you need, and I don't think it works with white as well because it becomes transparent. HTH!

You can also Mack-tack or tape the back of the ribbon.

I found that sticking it to clear contact paper and then cutting the contact paper to the size of the ribon works well. Marilyn
