When I saw this picture, I had to tell you about peach pip (or pit) flooring. It was first used by settlers in South Africa - the peach pits where set in various materials like ox blood & cow dung, clay & aloe sap, and wax. Today
Stone Fruit Floors uses glues, resin, and urethane. It is all installed by hand and has a low carbon footprint (at least in South Africa). All the sharp edges are filed off for barefoot comfort, and colors can be added to the resin to customize the application. Peach pit flooring can also be install on walls, stairs, exteriors, and even showers. I can't find a USA supplier... But I will keep on the lookout, because this is one of the most interesting flooring
materials I have ever seen!
