The 2023 Wimbledon creation was done with a towel dipped in paint and raked out to look like grass. Markings were taped off so I could create the lines. The ball as dipped in paint and adhered to the line. For tennis fans, one of the most exciting points can a be a line call and much debate can ensue, especially if there is no Hawkeye. A tedious creation but one of my favorites.
