Reply Buttercream with Fondant decorations?

I am totally willing to do a test run, just not sure where to start in order to get results I can work from. I guess I was wondering if I would be able to “pin” the drape into the buttercream at the tope of each drape, and then use the flower to camolflauge the pinned area? Is sugar glue something that you make or is it something I should look for tomorrow when I go to the cake store?
