I made this crazy drawing with an 8 pack of crayola markers, one disposable pen, and a sheet of printer paper.
Cheap art supplies are great. They misbehave and lower our expectations. Enter: risk-taking, the star of fine art.
Sure you give up certain visual qualities... but that isn't a limitation. Also your artwork won't last 200 years.
Go grab some crayolas, and be fearless!
Do you ever use cheap, worn out, or broken supplies and tools?
