Screwed

A broken ear greets me in the morning. A warning sign from the clay gods that my armature was not adequate for my dear Amelia. I poured myself a cup of ambition and fearlessly removed both ears and replaced them with 3″ drywall screws. Drilling pilot holes and firmly screwed into the wood finial below. Now to figure out how to cut off the screw heads so I can sculpt ears over them?
