Happy puzzle day.
I enjoy assembling jigsaw puzzles, but I never know what to do with them when I’m done. Do I hang them in a frame or break them apart and put the pieces back in the box? Neither seems very satisfying.
What is satisfying is watching puzzles being made at the factory. The design of the pieces is not random but carefully designed.
Check out this Britannica video to see how jigsaws puzzles are manufactured. It isn’t a puzzle, but it is fascinating to watch.
