I like buttons, and I like them even more when I can make them out of unusual materials. While rummaging in the patch of trees behind the neighborhood, I found part of a countertop … even remember the people who installed it 15 years ago or so. To start the process, I cut off a piece from the main counter and then cut that piece closer to button-depth. In the second picture you can see where the buttons came from. I roughed them out with a coping saw and then used the big piece and a clamp as a jig to perform more fine sawing (also second pic). I’ve scrapped these buttons, however, because they are too thick; a belt sander would shape quicker, but mine’s without a belt.
