I'm a big steamer.
Wow, that sounded wrong, lol!!
As someone else said, I just don't push the iron around unnecessarily. I've found that lots of times, steam can help you fix issues, especially if you're dealing with bias. I recently made a quilt from jelly rolls, the block edges were ALL on the bias. I glue-pinned the seams so they would match, then steamed the blocks, holding the iron about a quarter-inch above the fabric. All those bias edges snapped their heels together, saluted me, and lined up perfectly.
