Possible, too.
Impossible, but someday...
But all that has changed, since we got Naia, my older gran-daughter, puzzles, and worked with her on them.
The second puzzle (last photo) was three years her senior, so after awhile, she gave up, and we did too.
I was too challenged by it not to return to it. When Naia saw me working at it again, she returned to her age-appropriate puzzle and succeeded, twice. We exclaimed, "Yay! We did it!" and "Give me Five!"
Yet I was, very quietly, rebuilding my own big picture...until it was done.
Now, I've got to find a proper table for the jigsaw puzzle.
