I spread old beach towels on the floor to absorb the over-spray, and spray pieces of fabric with 50/50 Sta-Flo/water until saturated, and just let them air dry on the floor.
I usually starch what I need tomorrow and let it dry overnight, and never have flaking because the fibers absorb the starch.
If the pieces are large, I will soak them in the starch mixture and wring out the excess then spread the yardage on the towels to air dry.
I seldom try to iron the fabric dry. Just takes entirely too much time!
