I used to use spray starch ... ALOT buying 6 cans at a time. Now I used the liquid concentrate and immerse my fabric, its much cheaper and I can adjust the amount. Immersing gives a more even application of starch. I mix my own "spray" from the concentrate and keep it on my ironing board for those quick needs. I will admit I rarely sew anything that is not starched. Once you use it ... you will not want to be without it.
Starch is making a good quilter even better!
