We made custom tables out of reclaimed black walnut from a 80 year old barn we found in North Carolina. We used conduit pipe recycled from the construction site. The branch going up the middle of the table is from a dead Wisteria tree we found on a hike. We used a salad bowl finish on everything since it was food grade safe for the coffee shop. We chose this wood since it was native to the region and had coffee tones in it.
