This is actually the third room that I restyled, but the bathroom is not fit to be photographed, so I'm skipping it for now. This room is an upstairs bedroom that was originally part of the second-level attic (there is also a third level attic) and was converted in the 70's to create a fourth bedroom to accommodate the previous owners' four children. Since it wasn't part of the original living space, there was no plank flooring under the pea-soup carpet, just plywood subfloor. I wanted to lay hardwood, but carpet was less expensive and easier to install, and as my husband pointed out, cozier for on-the-floor playing (for the kids, not us).
This wasn't a high-priority room, so I did my best to use furnishings we already owned. The old slate chalkboard was in the upstairs landing, along with the vintage desk, and a schoolhouse light fixture that I convinced my crabby electrician brother to move into the play room. There's also a huge bookcase that was in the room we use as a master bedroom, which we screwed into the wall and filled with toys and books.
The curtains were made from fabric that a friend bought for me
years ago from the Ikea in New York when I was living in Miami and had never heard of Ikea. For wall art, I opened boxes that we'd never unpacked and found prints and a vintage linen childrens book and put them in inexpensive frames. I also used some self-adhesive racing stripes that I found at Lowes for a few bucks.
Add jalepeno paint, one excited kid, and his Plan City, and we now have a Play Room.
My husband built our son a sandbox that's designed to look like a car. He used scrap wood he found in our barn and a couple of new boards from the local lumber store. He added a few coats of orange opaque stain, and I painted some headlights, taillights, and tires to finish the look. It reminds me a bit of a vintage Land Cruiser. We parked it off to the side of the garage in the shade of a gigantic spruce. The kid is so happy with it that he woke up this morning asking for the sandbox, so I'm either going to have a big problem or a wonderful diversion on my hands. 
Knowing my boy, it'll be a healthy dose of both.
