Of all the puzzles I have ever made, this one probably is the hardest but also the most satisfying. It took me a total of 13 hours over 2 days (which is not the longest a puzzle has ever taken me -- before discovering these beautiful wooden puzzles, I would typically make more conventional "jig-saw" puzzles of many thousands of standard cardboard pieces, consuming many more hours). In this puzzle, the pieces lock together in a way that was new to me -- the hooks at their corners whirl together, four at a time, in a vortex that anchors them all solidly once all 4 are in place; the edges of the completed puzzle are scalloped, so that edge pieces are not a priori distinguishable from the interior pieces. The jewel colors of the painting by Erin Hanson fit together perfectly in this stained-glass-like picture, but vary so quickly to make it impossible in almost all cases to find the next adjacent piece just by looking for continuing color fields. Most pieces I placed by studying first the piece and then looking for the exact location and orientation for the piece in the picture on the box -- a study that made me understand better the physicality of the painting (shadows of paint ridges on brushstrokes with slight impasto), and made me appreciate some of the painterly composition (strokes in the grass and in the sky point, on average, to vanishing points on the horizon). After completing the puzzle, I now feel exhilarated, not only because I managed to complete it (despite my initial fears), but also because it unexpectedly has taught me something new -- always a wonderful experience.
