Ok, so I'm making a bridal shower cake next weekend. It's just a one-tier 10" square, and it'll be frosted in BC. I want to put a ribbon around the bottom as shown in these pics:

But I'm not sure how to get the bow look w/o squeezing too tight & squishing the cake (if that makes sense). Do they just make the bow separately & the attach it to the ribbon? Help please!!! Thanks!

Definitely make the bow separately and attach after the border ribbon is placed around the cake.

First - if you are using a BC icing be sure the icing has a slight crust. This will prevent any seepage onto the ribbon.

With a small dot or two of BC or gel, attach one end of the ribbon to the botton of the cake and gentle wrap around the cake and add a dot or two again to connect the two pieces. Make your bow separate and attach it with a dot of BC to the ribbon that is on the cake. ( you can hide the junction of the ribbon under the bow) Hope that helps.... post a picture of your finished cake.

I absolutely hate putting ribbon on a square BC cake. It tends to cut into the icing at the corners and that makes it look sloppy! One way to help prevent that is to cut strips of card stock paper to fit, in other words the same length as the sides of the cake, and attach that to the back of the ribbon before placing on the cake. This will give it some substance and help it not cut into the icing. And yes, definitely do the bow separately.

Thanks all!! And thanks Melvira for the tip...
