Here is a little tour of my hand tools for making stained glass pieces (and the ones I am using for this step of the process). Sorry for the lousy quality of the photo.

Top left - Glass cutter
Middle left - Sharpie (like you couldn't figure that out)
Bottom left - Breaker/grozer pliers
Upper Right - Scissors for cutting the pattern (only needed for the first time making the pattern)
Lower Right - Glass with pattern piece
Underneath tools - Several different pieces of glass that I am using with this project.
Underneath everything - newspaper for cutting on
