If you are a stained glass artist and don't have a rebar bender, you should think about investing in one. They cost around $100.00 and they are well worth the price. Without one I would not have been able to reinforce this window along the curved lead lines of my design.

Some of the angles are extremely tight. The zinc rebar is very strong and nearly impossible to bend without either heating it with a torch (you can also use friction by pressing down hard against the flat side of the bar and passing it back and forth against the edge of your work bench--time consuming!) or using a bender.
