Hi and welcome to this board, lots of friendly, helpful people on here. I always wash and dry my fabric as soon as I get it home. I fold it and roll it on my ruler and store it. When I am ready to use it I iron it with steam, on the lengthwise grain and use it. I recently started pressing my piced blocks on the wrong side, I use steam on the right side, seems to make it sharper. Pressing is only moving the iron Up and down, not moving any other direction.
