for a cake box? I am making fil a b-day cake later this month and I need to be able to hide it at a moments notice when he comes (he does sometime stop by without telling us). If it were a cake box sitting on the table he would probably peek. the cake will be about 12x15 inch and about 4-5 inches tall. I will be using fondant so I can't hide it in the fridge.

the only thing i would suggest is a regular packing box that you purchase for moving.

Don't leave it sitting on the table where he can see it.

My mom gave me a really good idea, a storage tub! I happen to have one about the size I need I just have to empty it out and wash it. I will probably have to line it with something so that fil can't see through it though.
