Simple stack of multiple fabric-covered foam pads. makes a cushy "sofa" in the playroom, and can be pulled apart for multiple sleepover guests, movie night pillows, or tumbling games, etc. (they have fabric covered foam mattresses at Jysk)
DIY Kids space reading nook~ Rain Gutter Kid’s Bookshelves This could be the best 're-purposing' project I have seen so far.what a great idea and the books, or whatever, would not fall off the 'shelves'.
Mommo Design has a bunch of inspiration for girly reading nooks. These quiet corners contain fluffy pillows, rugs, cushions, usually a canopy, and of course lots of books. I think the idea is very cute and I'd love to do this for my daughter's room.
