Than comes the fun part finding the piece you want to do. I would recommend second hand stores, consignment stores, garage / yard sales, Craig's list, or old furniture that you have that you don't want any more. I found this desk that I could tell had lots of personality. It cost me a whole $4.50. I had a place in mind that I wanted to put it (I didn't end up putting it there, but have some place in mind). I started by sanding. There was a lot of grime on the top so I sanded the whole thing really well but I was told that you only need to rough it up a bit.
Next is choosing a color. For this piece I chose black, but it was a toss up with red....really you could do any color that would go with where you are going to put it and the look you are trying to go for. I painted the whole thing with a primer. Then I put 2 coats of black paint. I went back and forth wondering if I should do another coat but decided against it.
We than sanded all the edges with a palm sander. Some of the spots we brought all the way down to raw wood but then others we just did lightly. I decided not to sand any spots on the top but you could do that if you desire to make it look more worn. We than coated the desk lightly with a gel stain. Make sure that you apply it with the grain.
