I covered a dummy cake with coloured sprinkles DJ…and there were sprinkles everywhere!! I did put a old towel on the floor anticipating a mess. I’ve never actually done sprinkles or sparkling sugar on bc cake, except for a very small area. I hope someone here can give you some good hints. Either way, think it’s going to be messy. Unavoidable hazard.
