I want to try a bird.
This is a tracing from an earlier blog photo onto gesso with Saral, then firmed up with silverpoint. I used graphite on the corn and some little carbon particles seem to float about the tempera. Then I inadvertently smeared my palm across some tracing. What a mess! I was hesitant to remove graphite with erasers, fearful of contaminating the gesso surface. The only method I've found useful for removal is sanding.
