What's useful to me:
1. a good heavy steam iron. The weight, if you don't mind it, helps get the wrinkles out quickly.
2. a bottle of water with a fine spray nearby. For getting out "mistakes" where you've ironed in a crease or for when the steam alone isn't enough.
3. a clean smooth dish towel or pressing cloth. For use on delicate fabrics or anything that might turn shiny using the direct iron.
Method I use:
1. I turn most things, especially knits, inside out to press them.
2. Start with collars, then sleeves, then yokes and shoulders, and the body of the shirt/blouse last.
3. Pants I also iron working top to bottom.
4. Downey wrinkle releaser or Fabreeze used the same way is a great timesaver, especially on items that need a re-pressing.
5. Use the time to engage your mind by listening to a good book on tape or TV show that's a guilty pleasure or meditate or talking to a friend on speakerphone...anything that's pleasant and a treat for you in your busy schedule. You'll come to look forward to ironing.
