I don't know about the binding, since I have only added binding to one quilt! But, my other little quilted items still have a nice "antiqued"/crinkly look even using prewashed fabrics--(well after the item has been washed/dried on completion). (Using cotton batting, Warm and Natural). So, maybe try a little piece with prewashed fabrics and see if there is much of a difference? I know I would have to hate to redo something once I was supposed to be done!
