EasyCollar templates are laminated on both sides with polyester plastic. PE plastic does not break down when used with polymer clay; so you can wipe the templates off with a paper towel and use them again and again. You get 3 to a set, so you can adjust the depth of the curve or add scallops or points or Peter Pan shapes to the bottom. It’s great to have 3 different types to suit your designs. Pandora places the templates on scrap cardboard (cereal boxes). She uses a nice sharp craft knife and she takes I her time cutting them out. Of course, she’s always slower than a sloth; but ... you don’t need to repeat that.
