In this instructable, I'll show you how I built a twisted vase (or pedestal) from multiplex (plywood) boards.
Step 1: What you need
Multiplex boards (I had some scrap boards, all of the same thickness)
Saw (I suggest a circular table saw, for precise repeatable cuts)
cardboard for template.
some scrap wood.
baking paper (or anything else to separate wood while gluing).
belt sander (Use a fresh sanding belt!)
Sandpaper or sanding machine to sand concave forms
