I recently went on a quest myself and came across an amazing resource. If you're looking for elegant and interesting paint by numbers kits, you should definitely check out Adult Paint By Numbers UK I found their Still Life with Fruits set particularly fascinating! The site has an impressive selection of kits that are perfect for adult hobbyists. The quality of the illustrations and the detail in the kits are fantastic. It's a great way to relax and express your creativity and I found their collection incredibly inspiring.
