While I can work in lead came, all of my "production" pieces are in copper foil. It's faster to use and a lot less fiddly. The biggest tip is don't get frustrated and don't expect it to go right on your first (or 5th or 10th...) piece. Glass will break, glass will cut, solder will glob. It's the nature of the craft. Just keep plugging away at it until you work out what feels right and then everything will flow properly.
Other than that, read all you can on the subject. The internet has answers to any question you might have.
