Reuse Old Paint

I painted my small house with big cathedral ceilings about ten years ago, a nice off white that caught the sunset from across the river. Since then I've been sitting here smoking a lot and once I boiled Maple syrup on the stove inside (you only do that once). The walls and the ceiling are basically maple brown now. After all these years.

Rather than paint these walls again I decided to "reuse" the original paint. I mean, "green" and all that, right? So I searched on the Internet for ways to reuse paint. Here's what I found:

Materials
----------
1/2 Cup of Borax
1 Bucket
1 Old Rag

Directions
-----------
1) Put Borax in Bucket of hot water.
2) Wet, wring and rub rag repeatedly on wall until done.


So this was really excellent. Now I have new (looking) paint on a lot of my walls (there are some left to do) and it only cost me about 20 cents worth of Borax (and some time, but I was bored anyway).
