I wash, then air dry all newly added fabric. I have learned not to iron until I'm about to make use of the fabric. I don't starch - have you tried sewing or quilting once there's starch on the fabric? egads! Talk about needing pliers to pull thread through! If you're one who sends out quilts to have binding put on, due to no fault of your own for not liking the binding part, think of the poor soul who has to put that binding on once starch has been used....it's a crime I tell ya, a crime!
