Cartonnage tool for making corners

A couple of months ago, I wrote about a corner miter tool I saw on-line. A couple of people have asked if I knew of a pattern for it and a reader on Facebook suggested this plastic one. Then the other day I saw Claudia Squio (ColorWayArts) corner miter tool, made from stainless steel. Much more durable than anything I can make from book board.

She calls it a “cartonnage tool” — cartoonage is a new word for me. Wikipedia says “cartoonage,” as a technique, is “similar to papier-mâché, (where) scraps of linen or papyrus were stuck together with plaster or resin and used to make mummy cases and masks.” On her blog, Claudia says “Cartonnage, originated in France in 1800s, is the art of making decorative and functional items out of cardboard, covered with fabric or paper and it is a creative and stimulating hobby.”
