I prewash all my fabric -- if for nothing more than to get all the chemicals out of it. I dry it in the dryer but do not iron i. I then ruler fold it and put it in the right drawer. I iron the fabric just before I use it. Then I will also use starch. I'm not going to waste my time ironing right after washing if I'm going to put it away. It will need to be ironed before it is cut anyway.
