  1. Digital painting by numbers: With the increasing popularity of digital art, it is possible that painting by numbers could also become available in a digital format. This could involve using a digital canvas, paints, or a software program to fill in the numbered sections.
  2. Custom painting-by-numbers kits: Some companies may begin offering the option to create custom paint-by-numbers kits, allowing customers to choose their image or design to be turned into a painting-by-numbers project.
  3. Collaborative painting by numbers: Another possibility is the emergence of collaborative painting by-numbers events or projects, where groups work together to complete a picture by-numbers canvas.
  4. More complex painting-by-numbers projects: Some people may be interested in more challenging painting-by-numbers projects with more elaborate designs and a more significant number of sections to fill in. This could appeal to those who want to test their skills further and push their artistic abilities.

Overall, the next big thing in a painting by numbers could be anything from a new technological development to a shift in the types of projects offered. It is impossible to say for sure what the future will hold for this activity, but it will likely continue to evolve and adapt to the changing interests and needs of those who enjoy it.
