I'm also exposing you to my dust. Just remember, if we focused a camera on your steps, they would probably be dirty up close, too!
The whole process only took me a little over 2 hours - 15 minutes of that time was me lying flat on my back in the living room because there is a lot of hunching and scrunching and crouching involved in this project and my back killed by the end. So DIYer beware. But all-in-all, it was actually really easy.

-Hot glue gun
-metal yard stick or straight edge
-Sharpie or pen
A few tips:
-Measure twice, cut once. Only had to make that mistake once.
-Measure each step individually. Don't just assume each step is the same, especially in an older home. My shortest step was 6 1/4" high and the tallest was 7 3/4" high. They all visually appear the same, but weren't.
-Don't make your pieces too large, or it will be hard to get them to lay smooth. It won't be noticeable if you come in 1/8" here and there to make sure it fits.
