How to Draw/Cut a Circle without a Template

This is a good option when you don't have a speaker's cut out template. It will allow you to draw a circle to use as a cut out template.

The full circle method

1. You can use a sheet of heavy-duty paper or do this right on the drywall if you can. 
2. Cut a piece of string about 4" - 5" longer than your radius. We used a 10" length of string for this cut below. 
3. Tie one end of the string to a short pencil. 
4. Place the point of the pencil toward the outer edge of the paper with enough room from the edge to make a full sweep. 
5. Measure from where the point of the pencil touches the paper backwards by the length of the radius (in this case 6½"). 
6. Pin directly through string into the paper or drywall at that point. 
7. Keeping the string taut, draw a perfect circle using your homemade compass.
8. If you used the paper, cut the paper and you now have a paper template. If you use the drywall, just cut out the drywall now.
