Where quilting is concerned, I'm a no steam girl. I use starch to iron my fabric before cutting, and I rarely need to use anything more than a hot iron after that while working on blocks. If I have a stubborn (thick) seam (like when PP), or if I accidentally iron part of a seam the wrong direction, I'll give the seam line only a little spritz of starch and iron.
I keep a second iron that I use when I need steam. Working with wool applique is a good example. Also of course my clothes.
