I just made my first attempt at tennis shoes. I had to make four of them. They are for my son's and his best friend grad cake tomorrow. I took the individual rkt that are in the package and just shaped them like a shoe. Then I put black fondant over just the tops. I used my cricit. It has a shoe cutout. I cut out two had them meet in the front and the back and used gumpaste glue to hold them together. I added the school colors , put a trim and made laces. Actually I think my first one turned out the best. I will take a pic tomorrow and try and send you a pic monday. Sorry it can't be sooner but with graduation and the all night party I won't be home until monday.
So in the mean time maybe someone else might be able to help too.
