The starch that I use is the one where you mix it with water to make it what ever strength you want to use it at. I of course go for the heavy starch where you can make a 4" square stand up on end. I used an old "Shout" spray bottle and I was thinking that might be it. I modified the sprayer to where it is almost a mist and I wait for a while before ironing but sometimes it still flakes.
I was thinking that the starch was a little too heavy.
