I'm freaking out a little. I'm trying to glue ribbon to my cupcake stand and it's not sticking. The stand is styrofoam and the tops of the tiers are coated but the sides are unfinished. I am using a clear gel craft glue. I originally had ornate braided trim, and when that wasn't sticking, I thought maybe it was just to heavy, so I'm trying to use a metallic ribbon, and that's not sticking either. Any suggestions??
