Columns

Paint-ready decorative columns built over a Sonotube concrete-form tube, with a wire/stretch-wrap/tape/paper shell.

Layer stack

From the form outward:

1. Sonotube — the round cardboard concrete-form tube, used as a reusable template/mold (8 ft tall, 12” diameter). It’s removed after each shell is built and reused for the next column, not left inside the finished piece.
2. Wire — 1/2” hardware cloth wrapped around the tube, closed with zip ties, for rigidity and texture.
3. Stretch wrap — heavy-duty shrink/stretch film over the wire, smooths the surface and acts as a release layer.
4. Carpet tape — double-sided tape over the stretch wrap, gives the paper layer something to grip.
5. Paper — kraft butcher paper pressed onto the tape, forms the paintable outer shell.
6. Paint — tempera paint applied last with the foam brushes.
