Chain maille: You have some choices; I've posted free tutorials on the right side bar. You can buy tutorials at JewelryLessons.com, bless them for trying to make a buck with copywritten designs they sell, or you can go to the chain maille organization and get TONS of instructions on all kinds of patterns, techniques and so on all for free.
The newbies jewelry designers/artist coming on board everyday should really do some research on "how to's" for free before you jump into buying tutorials that actually have been copied from magazines and other free tuorials posted all over the web.
Wire wrapping: for the most part you can find easy to follow instructions all over the place if you are new to the craze. More advanced wire wrappers can look at something and duplicate it. Good Luck and above all learn something new everyday.
