Lead lighting

Mum used to do this, and I have always thought it looks cool, or at least has to potential to. As my house isn't 'period' I think I would have to be very careful with how any lead light was implemented, other wise it could look a bit .... dumb. But there is no harm in doing a course. Here is what I am thinking of going with. I am also thinking I might change one of the other 'course' task to this (cool glass bead making!).
