Alright, maybe I'm stretching that a teeny bit. I'm not sure that organizing a closet full of clothes is ever fun per se, but it will make the closet more fun to look at!
Sold via Franklin Covey, closet dividers by O.R.E. Originals come n a variety of prints including the Big Dots (shown here), Fairies & Berries, Hoot, Les Petits Enfants, Matryoshka Dolls, Gingham Checks, Retro Robots, Cars, and Numbers.
While you're on the site scoping these out (which, by the way, cost around $10), check out the other very cute baby clothes organizing stuff on the site which includes wet/dry bags, clean/dirty bags, laundry bags, and a day tripper bag that can be used to store all sorts of baby clothes when you head out on vacation.
