This ruler from Creative Grids also has the ingenious anti-slip backing, which grips perfectly under pressure and thus prevents annoying slipping when cutting. With this ruler, you can conjure up half square triangles and quarter square triangles in four different ways. Take a look at the linked video! Of course, illustrated instructions are also included.
