I agree the ratio is way off.
I love 'Mary Ellen's Best Press' (fragrant free) but because of the cost usually mix my own starch using 'Stay-Flo' with a 1 to 1 ratio with water.
I have tried the Niagra starch in the pump bottle and like it much better than the aerosol. However, as I can only find it in the linen scent I can't use it. It has a lovely Linen scent but I am allergic to things with fragrances.
