Sepia ink on smooth cardstock. Materials are archival, as always.
Standard ACEO size: 2.5 x 3.5. Card is an original and signed on the back.
I don't begin these doodles with a design in mind. I draw random lines to divide the card into sections and begin filling them in with patterns. I choose patterns based on what appeals to me, and the patterns I see around me. The cards evolve as I go.
Certainly not a novel process, but I'm enjoying it.
