There are still a couple of things to do, namely do a bit more decluttering of drawers, shelves, etc., and the removal of some storage boxes (not pictured) that I am hoping to find a home for somewhere else at some point. In addition, I still haven't managed to buy LB a new desk and though she is happily making do with an old IKEA table that was once a desk when this room was OH's office (before the basement was renovated), I would like to uphold my promise to her at some point, as a smaller desk would give her a bit more space in this room.
Anyway, without any further ado, here's the before pictures from my original post which is a slightly sanitised photo of her bedroom when it was originally redecorated nearly 3 years ago
and here are the after pictures of how it looks now.
A bit more 'Tumbler' as LB would say. She seems very happy with the results and so far is managing to keep it pretty tidy which is a bonus. Definitely worth the effort and very minimal costs of less than £50.
