Avoid working over carpet because of the risk of getting glass shards on the floor if the glass breaks. For their own safety keep pets and children away from your workspace and materials.
Cut should not be very long. Scores longer than two feet have a high failure rate when breaking. Make sure your marks leave about six inches of glass on each side to grip and break. If you cut smaller pieces, you may need to use special tools, like pliers or a light hammer, to break off glass you can’t get a hold of.
If you push too hard (a very common mistake), your cut gets “hot,” meaning that it snaps and pops. You are aiming to get a uniform score. If you are pressing too hard in one spot and perfectly in another, the glass will not break the way that you want it to. Microscopic imperfections in your score will cause your cut to go askew.

When the glass breaks, it may simply start as a “run. " If it only runs an inch or so, apply a little more twisting pressure and it will continue to run.
