Knotty Alder wood is light tan or light brown with a yellow or reddish ting. The fine even texture and moderate density of alder wood makes it easy to work with. Alder sands and polishes easily, stains readily, and seldom splits. We use only the higher quality grades of knotty alder lumber for our products.
