I use the Fiskars large hexagon cutter from the Scrapbook section of J's. I just use leftover cardstock. I think it is 1 inch. There are 3 sizes. The large one accommodates a 2 1/2 inch square easily. I have had the plastic templates with the hole in the center. The hole just makes it easier to pop out the plastic. Never tried to glue the hexie to the template.
