Mesquite Board M-1009
1.8"x 1.1"x 5.7"
This is a small, attractive Mesquite board that has a mix of heartwood, sapwood, and a small sliver of bark. The front face (first photo) is nearly entirely heartwood, whereas the back and sides show more variability in color and texture.
The back face has some surface mottling that is a darker color. It is a natural feature of the wood, and it appears to be about 1/8 inch deep. If you prefer, you can easily plane off this darker patch.
