HOT TOOLS CURLING TIPS?

So I just recently got a Hot Tools 1 inch curling iron, and I'm wondering how I should use it.  Do you have any tips for different ways to do voluminous curls, tight curls, or just every day curls? I'm looking to get a couple of different looks.

When I use my 1 inch it is to add volume, toss in a few loose curls or control the hair around my face. I use a little mousse at the roots when I blow dry and then curl the roots up and back a little. I have very straight hair so it doesn't push it up a lot but it is a nice boost to volume. For some loose curls I just use the iron vertically to get more of a loose ringlet and then curl the ends.
