Eppiflex ClamshellsEppiflex clamshell measurements are across the diameter of the clamshell. Transparent for fussy cutting and precise positioning. Strong and durable reuse again and again just wash them in the washing machine! Laser cut for precision for more accurate piecing. Cut with a patented design which enables them to bend when you need them to. Heat resistant, so great for our starch now, sew later technique. Hard at their edges no more sewn in card. Templates
