This project is relatively easy, a great way to practice with natural edge forms without the risk of a bowl. These coasters are wet, freshly harvested, cedar. After slicing a limb into discs, I started them drying with a quick soak in Denatured Alcohol to accelerate the drying process. They had lost about 30% of their weight before I started turning them.
Then in a quick but repetitive process cut a mortise on the bottom, smoothed the rim wood and smoothed the top surface.
Later I realized that they were reversible — the mortise was large enough to hold a cup or mug.
These coasters are irregular size between 3 and one half to four inches and finished with walnut oil.
