The process of making stained glass light is actually quite simple. First, you need to gather your materials. You will need a sheet of glass, a lead came (a strip of metal that holds the glass pieces together), and a tinning kit (which helps to adhere the lead came to the glass). Next, you will need to cut the glass into pieces using a scoring tool and a straight edge. Once the pieces are cut, you will need to fit them together like a puzzle, using the lead came to hold them in place. Finally, you will need to solder the joints between the pieces of glass using a soldering iron and lead-free solder. Once everything is soldered together, your stained glass light should be ready to hang!
