The process for creating this spoon can be found by combining the methods described in the following two Instructables: Spoon Carving for Everyone and Scrap Wood Cutting Board.

The spoon pictured below is made from (left to right) Cherry, Maple, Walnut, Cherry. It has a sizable handle and a broad head to scoop large amounts of the aforementioned delicious salad.
