Hey Dave, Like GB said, look in the carpet section at HD. I used to use two sided tape a lot for stack cutting, but I always had a problem with separating the layers, often times breaking small pieces. I now use either a hot glue gun to glue the edges of the stack or blue painters tape. If I am cutting the piece from inside the stack, I use the hot glue gun. If I need the outside edges for the piece, I use the blue painters tape on the edges to make up the stack.
