Great colour choices!
I have no idea how long it's going to take me to organise the kids rooms! Forever a work in progress, I think!
The Expedit shelves are GREAT! I am thinking we will have to get some more for DD's room now, with the purple boxes for her. Are you having all your 3 in the tv area?
I hadn't thought of staggering them... I do like them in a row like that ... I like the idea of all the books along the bottom, then the next row the storage boxes, at a good height so DS will be able to reach them ... then the shelving, with the 'good' stuff up high where he can't reach without me being there. But it's an idea for later on if we ever want to 'shake things up' in there!
