If you have a project that calls for a perfectly drawn circle and you don't have a compass, worry not. You can draw perfect circles of all sizes with a few basic office supplies or using only your hands.
In the video above, youtuber DaveHax demonstrates all the ways you can draw a perfect circle without the proper tools. The simplest ways are to use your wrist bone as a pivot point and spin the paper around underneath it, use any of your knuckles as pivot points, or use your finger tips as pivot points. But you can also make an impromptu compass with three pencils and a rubber band, a strip of cardboard, a piece of string, or use two pencils and a paper clip adjusted to the radius you need.
Learning any artistic process takes a mental adjustment. Learning to draw requires a different mindset that making a spreadsheet. This graphic helps you recognise the broad steps to get started.
