The next thing was to place my circle on the grid to note the size. I punched a template for myself and noted the number of degrees it covered by pacing it on the cut circle's outer circumference.
That determined how many times I could punch around the circle.
I made about an inch and a half mark around the circle on the correct number of degrees and then punched. (Please forgive my typo that I did not catch!)
I was expecting great results but was still surprised with the outcome. Even the extra bits are symmetrical.
I am sure other corner punches would work just as well. So long as you are able to see through the punch for alignment.
Here are a few more stills of my punches.
If you have not seen the Vee-dio; you can watch it here.
