Bill Cutler's description :"The wood used in this puzzle has two layers - one side is dark and the other side is light. The solved puzzle is a slightly skewed version of the Finnish flag. (The actual flag is a dark blue cross on a white background.) In order to make the puzzle 'work', it is necessary that none of the pieces can be turned over, so their shapes must not be mirror-symmetric, and the area to be filled also cannot be mirror symmetric. The one exception to this is the rectangle in the...
