This Paint by Sticker Masterpieces: Re-create 12 Iconic Artworks One Sticker at a Time! was so fun to do! It really is a combination of paint by number and creating with stickers. I did the Girl With the Pearl Earring over about 4 evenings while listening/watching TV and relaxing. And It was relaxing like knitting or crocheting a project that you didn’t have to count or focus on too much as no thought is really required, simply matching numbers and popping the sticker shapes in place.
