Fabric Corner Cutting Guide

My son made his first design with ThinkerCad and designed this fabric corner guide for his mom. This allow you to easily measure, mark and cut the corner of fabric in 4 different sizes. The sizes are 1 inch, 1.5 inch, 2 inch and 2.5 inch It might be useful for other things. Note: The 67 is just something my son added as a joke.
