There are two older adults (retired). We do not usually work on the puzzles the same time but do share the same puzzle. At one time we had a different setup, using a 48" round table and we could work together, but now use a rectangular table with a bright shop light suspended over the puzzle for better light. My wife will do diamond art work if I am working on the puzzle. Without going into personal details, we are physically limited in the things we can do.
