One of my favorites - coloring the steps. Our steps are in terrible condition and do need to be replaced but that is not something that is happening anytime soon so I was looking for a quick fix. My solution - we had a stain marker that came with our Wal-mart furniture for the dining room and I decide that it would be a good idea to use that to color in the exposed area of our steps.
I think it came out really well. The best part of my adventure (besides the fact that it took up a lot of my time and made me appear "busy") was that I found that I was not the first person to think up this idea. While I was examining our steps closer than I ever had before, I noticed areas that had been colored already. Pretty cool but also tells me that these steps REALLY need to be replaced. :)
