I just purchased some 1" hexis from a vendor at a show. They are plastic and scored down the middle so you can fold them in half for half hexis. They also have two holes punched into them to pin the fabric to the shape for basting the corners. Once a hexi is surrounded by others you can remove the template. I had never tried EPP before getting these and I really enjoy working with them. I forgot how many I got in the bag, maybe 30??

She also has the shapes for the millifiore quilt and a corresponding diamond shape that is the same angle as the hexis.
