To make the mummy wrappings you will need a tube of white frosting, and a petal decorating tip (that's the one that makes a long thin line.)
Apply even pressure to the tube as you create the tattered mummy wrappings. Add as many or as few as you like. I'm not very experienced using this tip, but I think they are fairly convincing.
However, you decide to serve these, I can guarantee they won't last long. Enjoy!
