I've been reusing these for over twelve years and love them. I make the hexie and spray starch with the template still in place. Makes a nice crease, then I pop them out and reuse them. Every hexie is perfect. I have made dozens of 5o"x70" quilts to give away and 4 queen-size quilts for my family

they have tons of shapes and sizes and I've even had them make a special size and shape for me.
