I ordered a case of Sta-Flo liquid starch from our local grocer when Walmart stopped carrying it. I use it 1/2 starch & 1/2 water. If I want it stiff as paper, I use it 3/4 starch and rest water. You can fan yourself with it.
I found it worked best to spray the back of the fabric, let it sit for 5 minutes or so and then iron it.
Love the way it cuts then.
