I chose to use the foil method instead of lead came for my 30" x 18" window panel and am now considering the best way to reinforce it: horizontally as I would for a leaded window, or vertically as was suggested by another artisan.  I have the metal/copper reinforcing strips. 

Also, I'm now wondering if using foil was a good decision, so I need to know if it is possible to use lead came over the foil or would I have to unwrap each piece?
