Seventy-five percent of this puzzle flew together in a few hours, and then the last few bits--the stones to the left of the canoe, the stones in the foreground that tumble into the water, and the trees on the left, above the fire--took forever because every piece could have gone anywhere in any of those three sections. We did not anticipate just how interchangeable the pieces would be when we ordered the puzzle. One of us got frustrated and gave up, leaving the task to others. The puzzle is beautiful when assembled--colours are gorgeous and very vibrant and crisp--but we won't be keen to re-do this one anytime soon.
