I use steam but by iron has a control so I can use no steam all the way to full steam. I set it in the middle so not as much but some. I also use the ironing pad that is 1/2" wool felt pad and absolutely would not quilt without one of these notions.
P.S. You can buy the iron pad at $50 on line - way to expensive, or you can get the exact same item for about $20.00. PM me and I'll explain more!
