I originally got the idea from my old roommate in college. Yes, I have had this table for that long.
Before you pull off the contact paper guarding the sticky parts, you want to measure it out. I simply started at one corner and made sure to leave a little on both ends. After I got the right length, I cut the piece I needed from the roll (It makes it a whole lot easier to handle).
Using my card, I started to smooth out the surface and trying my best not to create air bubbles.
Tip: Make sure you do not pull off the entire back of the contact paper. It gets sticky, and I learned the hard way. Yes, I did have to start over.
Tip: If you do have air bubbles, you can pick the contact paper back up and try again.
