If you're just starting out, I suggest checking out
www.smartflix.com (where you can rent DVD's). There's a great DVD from Doug Remschneider (spelling?) that covers several beginning Boro techniques.
I also suggest starting out with just a few colours - and some clear. Having too many colours too soon can be confusing and frustrating, as each colour has it's own characteristics, and many possibilities. There's a bit of a learning curve to Boro colours - enjoy the journey, there is much to discover!
