Alphabet: A...B...C...D...

I'm right handed, but when I work with wire, I hold the wire with pliers in my right hand, and most of the bending / shaping is actually done with my left hand.  The lettering I use is just standard cursive.  Personally, I like it a lot more than the "sloppy" cursive that is widely available at scrapbook supply stores.  The secret to my lettering is in the crimping.  You will notice that I commonly crimp the wire and double it over itself.  Many of the lower-case letters are formed with the basic C shape (like the beginning of the letters A and D).  Obviously, you can do any number of embellishments either before or after the letters...
