At Mt Baker Puzzle Books the have some fine wooden Pentomino Puzzles, handcrafted from a different type of native northwest of America wood (like walnut, cherry, maple and much more) by Stan and Connie Bookman.
A pentomino is a shape created by joining five equal size squares at their edges. There are twelve possible combination’s and there are several thousand ways to assemble these twelve pieces into rectangles.
Next to the fact that these pentomino puzzles are handcrafted they come also in a very nice wooden cover which makes this an ideal present.
