I do the same thing but without the art work, just finished the first five months off 2024 on my yearly spread because i need to plan some leave, plus my January page and one focus items page. Bujo is the best, i also use a fountain pen for that extra feeling.
Nice! Yeah I can imagine getting bored of decorating every month so not having any designs would be nice as well as you don't have to think about it lol. Fountain pen sounds nice and very vintagey feel :D
Decorating is also a good feel, the brushes and the colors, sometimes I will draw a plant pot and color in the leaves
