In 2013, when I first started illustrating, I wrote a post titled, "When in doubt, cut it out," which emphasized how helpful cutting paper can be for shaping my characters. Since cleaning up my studio space a couple weeks ago, another perk for paper scraps would be free, no-pressure experimenting.
Although the difficult-to-cut corners, accidentally-torn details, and bends and warps of the paper can frustrate the heck out of me, these same problems liberate me. I've been treating it as a big Who Cares exercise. And, as the composition is whisked away by my cat jumping on my desk, I feel unattached and able to try something else.
