In Spring 2019, brilliant cartoonist Matthew Thurber offered his Patreon subscribers the opportunity to appear as a character in “The Gargoyle Carvers,” the latest installment of his ongoing Mr. Colostomy series. I couldn’t pass up the chance to be immortalized in ink, and I asked Matthew if I could have his blessing to create my own response strip, from my own behind-the-scenes POV as a participant in his world. He consented, and so I embarked up on “The Gargoyle Casters.”
