Stream and press , just up and down with the iron , no moving the iron across the fabric , while in contact with it.

i use starch and press with iron on dry most of the time.

I stopped putting water in my iron and just use a spray bottle filled with distilled water when I want.

I recently started doing finger press (or using a wooden press stick) during the block construction. Then I give it a firm press with the iron when the block is done. Using steam depends on how well the seams behave.

I have always used a dry Iron if I need steam I use a spray bottle. Ladies aren't spray bottls great! I remember using a sprinkle bottle when Ironing cloths. I still have mine.

I use steam, but press, not iron. I press all pieces the same, so I assume if any shrinking is going on, everything shrinks the same.

I like to use starch and press, not iron, both sides. But there's no right or wrong way, just the way you prefer.

I use steam but make sure to press - not iron! I think that is where the stretching comes in. Also do not move the fabric until the heat is gone so no stretching from that.

I use a spray bottle with distilled water too, like some others do

No steam but sometimes I dip my finger in a little bowl of water and just
dab those pesky seams that don't want to lay flat then press or I use a
small piece of damp cloth on the seam.
