We live in a small three bedroom house. Less than 1000 square feet. It takes some creativity living in what is by today's standards, well, small. But we love it. Less to maintain and easy to clean! The two extra bedrooms, however small, have to be very multi-purpose. I recently built shelves for our video collection which resides in our guest room, which also serves as the video game room. The shelves cover an entire wall and they're filled. The project was inexpensive, less than $200, but that was still more than I'd planned for it. Only by about $50 or so, but still over budget. But it just made the room look and feel so much nicer than it was with DVD's stacked up along the wall in plastic storage units.
The other bedroom is my office/yoga room/craft room and it was just so uninspiring for so long. It measures 10'x10' I think. I decided I'd do what I could with it on NO budget. So, using things we already had in the house like my spinning wheel and chair and the antique Singer which were already in the room, a recliner from a friend that I just got tonight, and an old White model sewing machine that was left in the basement when we bought the house, I think I did a pretty good job of giving the room some new engery.
I finally have a comfy room to sit in and knit or spin other than the living room. I'm so happy!
Here are some pictures of what the room used to look like not long ago and how it looks now. There's also a picture of the shelves in the other room. That project is still technically not finished since I have to level and bracket the rest of the shelves and stain/poly them. But we'll save that for a day when we can open the windows.
