I have not used this recipe but am interested. I generally use Niagra non-aerosol or if I have some Best Press. I starch similar to like we used to sprinkle clothes "back in the day". I put my fabric in a plastic bag and then spray the starch in the bag quite heavily. I then massage the fabric through the bag to distribute the starch and then let it sit a while for the starch to absorb into the fibers. The reason that I do it this way is so I don't have to deal with the over spray of starch which can be sticky on the floor, ironing board etc. Starch flakes when you iron it is because it has not been fully absorbed into the fibers and so when the hot iron hits the starch it dries quickly and flakes. If you wait until the starch is fully absorbed which is achieved in the plastic bag you will get little to no flaking. I'm impatient and it is hard for me to wait but found that if I do I get much better results and my iron doesn't get all gunky.
