This is the first puzzle we have put together as a family. I don't think we would go back to the easier 500 pieces after working on this 1000 piece baby. You would think the sky and roof are the hardest, but actually it was the flowers and the path. This is a very well-constructed sturdy puzzle! This one is about 8 years old. The pieces put up with dozens of almost-fittings and kept their sharp edges and didn't fray. For two people this was about a two-week puzzle which just shone after it was put together. We can understand why people frame finished puzzles, although we are not sentimental. It was emotionally hard to dismantle it. Now it goes to a new life at my mom's assisted-living puzzle table!
