Both side surfaced by double drum sander, then orbital sanded to 80 grit. Water misted, imagine how these will pop when a finish is applied. (both sides pictured) measurements shown in pics, thickness on bottom of piece. This would make a great table top, wall art, shelf, charcuterie board, resin project. Highly figured, including some cats paw, curl, claro, feather, nice color variation.Nice natural edges with some great spikes. Very strong and dense material. Truly beautiful and unique piece. A true conversation starter as a finished project. This item is made of walnut.
