Seven Ways to Draw Perfect Circles Without Compasses
If you have a project that requires a perfectly drawn circle and don’t have a compass, don’t worry. You can draw perfect circles of any size with a few regular stationery or with just your hands.
In this video, youtuber DaveHax demonstrates all the ways to draw a perfect circle without the proper tools. The simplest ways are to use the wrist bone as a pivot point and rotate the paper underneath, use your knuckles as pivot points, or use your fingertips as pivot points. But you can also make an impromptu compass out of three pencils and an eraser, a strip of cardboard, string, or use two pencils and a paper clip, adjusted to the radius you want.
