They're my morsbags templates Pol as given to us by Ivybags! They're perspex or acrylic sheet or something similar. She got a chap to cut up a sheet of plastic "stuff" and it made templates for bags with a fold at the bottom or a fold at the side. Plus a leftover bit that does as a ruler for handles. It's great - Masterclock would find it much harder to make his random bags without them. And they're great for drawing round.
