I have purchased the following frugal items for our new place mostly from Etsy:
For mine and Aaron's bedroom
For the livingroom, in a cute yellow frame
Two throw pillows for Amelia's room
For Andrew's big kid room, a map chalkboard decal from Urban Outfitters
Jacob's Pottery Barn Teen surfboard shelves. I saved big time by using craigslist. His are white and sea green
