"Better to press (up and down motion only, no sideways) than iron. Ironing (moving the iron sideways) can distort the fabric."

Semantics. LOL grin That's the point I was trying to make...stay on the seam allowance only!!
I will say, after 40 years of sewing using a normal steam iron, the Eurosteam has been a gift from heaven. Stretchy synthetics that normally won't take a set, make sharp creases under the steam press.
That and heat tacking (instantaneous and no pins or pin holes!) have sped things up enormously.
