Knotty Alder // Alnus rubra

Lumber contains tight, sound knots throughout. A soft, relatively low-strength, straight-grained, even-textured wood. Works well with hand and machine tools, but sharp cutting edges need to be maintained to prevent tearing the grain. The wood is rarely wider than 6 due to the small size of the trees.
