I received this puzzle for Christmas. Immediately loved it. I don't think I have ever completed a puzzle entirely by myself. No one else was in the house and, no, none of the pieces were lost. The edges were there and I completed it and started on the green section. Could not find one of the green pieces. I went to the next section and completed it but couldn't seem to get the blue section done so moved to the pink section which I also completed and moved back to the blue section. Discovered that out of a 500 piece puzzle I had received only 496. Your quality control is lacking and I was very disappointed. I was going to give it to the local Garden Club but, of course, now I will just throw it away. Perhaps you should have it printed and assembled in the United States. You can find my completed puzzle with missing pieces on Facebook.
