The pumpkin tato in the picture is made from a 12" square sheet of scrapbook paper. I then added eyelets and ribbons to help keep it closed and to give it a more elegant look.
The invitation inside the pumpkin tato is made from a sheet of cardstock. I printed the details of the event and then cut to size to match the hexagonal shape of the tato (overall size is approximately 7" wide and 5" tall).
