Tools:
- Glass cutter like this one
- Sharpie Marker
- Measuring Tape
- Straight edge
- Gloves
Step 1: Mark your cut. I used a sharpie marker and a straight edge.
Step 2: Lubricate the cutting wheel
Step 3: Score along the marker line. Make sure to score completely from one edge to the other. Apply firm, even pressure during the entire pass. Do NOT score a second time.
Step 4: Snap along the score line. They make a special tool for this, but applying even pressure on both sides of the score should be sufficient.
