I have used Magic Spray Sizing for the past many many years with WONDEFUL results!! Crisp clean pressing with NO flakes like I would get with spary startches....maybe becaused I would spray and then iron!! Can't do that with starch but you can with sizing.
I use sizing to press my fabric before cutting ( I do not prewash ), and use it each time I press seams and then again when the top is finished before layering the batting and backing. For a King size quilt, I might use an entire can. $.97 cents at Walmart, I buy 10 cans everytime i go shoppping!!
