One of the stages in the process of sewing just about anything is pressing. Pressing is fundamental and garment changing. It can scorch or shine up a fabric ( in the bad way…) or it can shape and mold fabric to contours of a body making it look professionally finished.
Pressing is aptly called pressing because that is exactly what it is. What it’s not is ironing! Ironing makes use of the motion of the iron going back and forth smoothing out wrinkles of your laundry, uncut fabrics, pre-made clothing and sheets and pillowcases (??…). When you are creating a garment, what is required is shaping and molding while not distorting the grainline, changing the texture of the fabric or pressing areas that should be left alone. I am a firm believer in an iron with some weight to it. Let the tool work for you (and don’t think that using a featherweight iron makes actual ironing easier or less time consuming). When an iron is applied to fabric, the heat actually unbonds the molecular structure of the fabric, relaxing the fibers and then rearranges them into an organized field of unwrinkled delight. Each fabric requires its own temperature. Too hot and some melt. Too cool and wrinkles remain. Linens need 400 to 425 F. while polyesters are down the scale at 300 F.
