Corner Cutters JR and SR are my own design and creation that enables you to cut out box corners accurately, Faster, Easier and Better. This is a fantastic ruler that you will use repeatedly for all your box corner for whatever project you are creating.
Using a 45mm rotary cutter, simply place down on the bottom and right edges of your fabrics where you need to cut out the box corner. Cut 1 (one) cut horizontally and 1 (one) cut vertically and the corner square comes out. No more lining up you existing grid ruler, marking with a marking tool, using scissors and cutting.
These Corner Cutters are also used with your gridded rulers to cut the corner from yardage without cutting into the surrounding fabrics.
Corner Cutters are cut from clear 1/8" acrylic (paper still affixed for better pictures). A lovely lady suggested the "cut in" sections in the corner and this concept allows the 45mm blade to cut to the inside corner, even with 2 (two) layers of fabric, which allows you to cut more than 1 (one) corner at a time, for even more time saving.
Corner Cutter JR cuts box corners 1", 1 1/2", 2" and 2 1/2" corners.
Corner Cutter FAV cut box corners 2", 2 1/2", 3" and 3 1/2" corners.
Corner Cutter SR cuts box corners 3", 3 1/2", 4" and 4 1/2" corners.
