I have done this so many ways depending on the situation but this is how I will build a form for the Bancroft totem. I’m starting with a builders tube from a Lowes. I cut it into 6 inch sections with a utility knife. One for every child that has passed this year. I made one section 2 ft high to bring the parts closer to eye level and protect the artwork. I made plywood circles the size of the inside diameter of the tubes with a center hole the size of 2 inch pvc plumbing pipe and attached them top and bottom to the builders tubes with brads. Each section has a piece of pvc pipe through the center. These sections are then covered with either hardware cloth or stucco lath. I attach the wire cloth or lath with rebar wire loops that I twist on the inside and pull tight with pliers. I attach the wire to the plywood with a staple gun.
