Our basement has been finished for years and the kids have had full control of the space for playing, arts and crafts, video games, etc. We had a TV down there, and our only other TV was in our smallish living room. So we have a small TV in the living room but kept wishing we could have a larger TV for baseball games and movies. So... one thing led to another and a big-TV purchase for the basement turned into a decorating job. I don't have "before" pics but the furniture was arranged differently before and the whole room was basically a dumping ground for toys. Now that my two oldest are teenagers and my youngest is 8, we were able to purge a lot of old toys and everyone now understands that Mom is going to be more strict about cleanup of the "new" room.

Here is the TV-area pic. The TV and stand are new. The coffee table is a kids' table from PB Kids with the legs cut shorter. Got the Ikea chair from CL, and the big square floor cushions from Crate & Barrel. The back cushions on the sofa were nasty, so I tossed them and replaced them with 3 king pillows in new shams from Target.

From a different angle:

On the other side of the room, I covered our art table (which is a million years old, first kitchen table DH and I had) with a cloth that matches the floor cushions (it's supposed to be a picnic blanket). The square thing on the wall, which is hard to see, is a set of 4 FLOR tiles which work great as a bulletin board. The art-supply cabinet is the old TV armoire. Removed the doors and added curtains from Target.

It's not exactly ready for House Beautiful, but it's a huge improvement!
