Here I have cut the duct tape pattern pieces apart with an Xacto knife, and I'm peeling them off one by one. The wooden disc leaves a hole for the eyepiece and its lens will go.
I transfer the duct tape patterns onto a piece of heavy cardstock, which after some fine-tuning become my final patterns.
Starting with the snout, I cut the leather pieces along with the stitching holes, case them in water and handstitch them together. While still damp I fit them onto the foam model to ensure a good fit.
