I only use a dry iron. However, I just learned a new trick the other day which I kind of
dismissed at first then decided to give it a try. After I finished sewing my block and
as soon as I finish pressing, I put a square ruler on it and leave it there until it cools
completely. You get a nice flat block. It really works. I noticed that it creates just
enough steam under the ruler. Don't worry... your ruler won't melt. Wish I could
remember where I saw this trick...somewhere in the blog world.

Edit: It's better to leave it for a few hours. Doesn't work if you are too
impatient. LOL
