Add Valspar's Paint Crystals to any gallon of paint. Makes it sparkly! I'm thinking of doing the girl's room a toned down, lighter purple with one wall sparkly :) What little girl wouldn't want a sparkly wall?
Some great ideas here - reading nook doubles as a bed, ottoman for a friend or book, shelving up top. Maybe the wood for the reading area could be two sets stacked and the padding doubled to make a 'real' bed from time to time? Bed ideas for Ayla.
