How do I draw a perfect circle on a square of plywood? Question
I'm working on a string-art project on a 3-ft square of plywood. It will have brass nails in a circle with different colors of string connecting the nails in a pattern.
I'm trying to figure how I can draw large enough circle on the plywood. I've thought about:
- Finding a bowl to trace, but none in my house are large enough.
- Using a compass, but again, mine isn't large enough.
- Freehand drawing the circle, but it comes out too imperfect.

There's a few ways to do it:
- Use a compass. I know you said yours is too small, but you can buy a carpenty or woodworking compass that is much larger (foot or more).
- Tie a string to your pencil, keep one end of the string fixed with your finger or something else (toothpick, nail, other pencil) while you rotate the pencil while keeping string taut.
- Fix the center of the plywood (for example, by pinning it down with a nail), hold the pencil in place, and rotate the plywood.
And, one for fun more than practicality: Hang a flashlight above the plywood. It will probably make a circular pattern that you can trace. You can vary the radius by adjusting the height.
