I'd had several ladies ask me about the flip flop cake I done for my oldest granddaughter's birthday so I found the link for you.
This cake is so simple and can be decorated anyway you'd like.
I used the template from the link. Everything on the cake was editable except for the silk flowers. I used twizzlers for the straps and candy to decorate the sides of the flip flops. My granddaughter was having a luau party so needless this say this fit right in with her theme and really did turn out cute.
