The rough sanding is nearly complete. A little more has to be done in the tight V areas between the branches. That requires using the pencil type sanding sticks pictured above. A narrow band of sandpaper is placed around the stick. Once an area of sandpaper is used up, the band is simply rotated.
You’ll notice that each pencil is a different color. (There are four in all.) They are also slightly different lengths as are the sandpaper bands. Each length is a different grit. The brightly colored pencils make it easy to quickly chose the right grit for the job.
