We bought this puzzle brand new, so we were the first to open the plastic bag. When we finished the puzzle there was a single missing piece (the hot pink in the upper left under the large sunflowers.)
So we combed the area and couldn’t find it. Making things slightly more difficult was we have the main bedroom carpet temporarily under the puzzle table while they work on the bathroom and it is pretty much the color of the typical cardboard color on the back of puzzle pieces. I went and got a flashlight so I could crawl around on my belly like a reptile shining the light at ground level. I didn’t find it.
What I did find were two other puzzle pieces that didn’t match the current puzzle. They were the two single missing pieces from the last two puzzles we did!?!
Hopefully we’ll accidentally stumble on the current missing piece when we drop a puzzle piece while working on the next puzzle we do.
