I buy the liquid starch at HEB and mix myself.
What is the brand of the starch you buy at HEB? There is no liquid starch available in any store I've been to in over a year. I find it at Amazon but way overpriced for starch. I've been using Terial spray diluted 1 cup spray, 2 cups water. I do still have bottles of Sta Flo I bought when it was discontinued but that won't last much longer.
