Finished wooden espresso cups, walnut and light wood.

I used a plexiglass circle template with a router bit and bearing to make the initial circle. But the depth was too shallow and I didn’t want to use an extension. I purchased some little sphere rotary burrs, rough and smooth for the drill and finished the rest by hand. I cut the exterior wood with a band saw and did a ton of sanding. I finished them with the natural finish Tried and True.
