After washing, but before cutting, I starch. If the pattern will have a lot of off grain seams (bias) I starch heavily to about the stiffness of paper to keep the fabric from stretching while sewing. Use care while ironing to follow the grain of the fabric as not to distort the shape. Sta-flo diluted about half starch half water in a spray bottle is less expensive to use than many other options and works well. Also starch from the back side of fabric to avoid flakes on front, then iron from the right side to draw starch into fabric.
