From the world of sewing comes this fabulous array of clever transparent rulers in a variety of shapes and sizes, including rectangles, squares and triangles. I use my 6″ x 24″ omni grid ruler for cutting out fabric with my rotary cutter. Quilters use them for cutting out quilt pieces in various geometric shapes. People cutting templates or marking tricky cuts will find these transparent rulers very handy as you can see the surface through the ruler. There are angles for cutting 45 and 60 degree angle on many of the rulers.
