Re-uploaded [here](https://www.printables.com/model/801128-quilters-corner-radius-cutting-guide-25in) for the sewing contest…

My wife is a quilter and uses these to cut different sized radius corners. She had bigger and smaller store bought versions but needed a new size for a pattern she was creating.

The guide is lined up such that the flat edges are in the corner of the fabric then you cut along the radius with a cutting wheel and get a perfect edge every time.

This has a 2.5" radius (5" diameter) and a hole for mounting to a peg board. You could scale it for any size but the mounting hole might get wonky. The mounting hole is chamfered on both sides.

To customize hers I embossed her company name into the top.

Notes:

Any material does the trick. Use ironing for a nice clean look on both top and bottom -- especially true if you decide to emboss letters on the top.
