To create a spiral wooden vase, start by cutting a piece of wood into a cylinder shape and then use a scroll saw to cut the spiral pattern. After the pattern has been cut, use sandpaper to smooth out any rough edges. Next, apply a wood finish to the vase to protect it from the elements and enhance its natural beauty. Finish by polishing the vase with wax or oil to give it a glossy sheen. For a professional–looking finish, consider staining the wood before applying the wood finish. You can also use a router to cut a groove into the wood which can be used to hold a string of beads or other decorations. Finally, seal the vase with a few coats of lacquer or varnish to protect it from scratches and further enhance its natural beauty.
