Alas, I have tried to finish my Harriet Tubman jigsaw puzzle but 8 pieces are missing. They could be somewhere on the floor or maybe somewhere in the debris on my desk. It was a production to find or make a space for this 500 piece puzzle so I am not surprised that there are some pieces missing. I shifted things around quite a bit to make room to do the puzzle. Okay I’m all set to do another puzzle, this next one is 20 x 20 inches. (the Harriet Tubman was 18 x 24 inches.
