i have to ask---why would you add any oils to your starch???i would think an oil would leave spots on the fabric-
seems like vodka would be an expensive alternative- my grandmother used niagra starch- i've been using it for over 45 years- and it is inexpensive..i don't quite get looking for more expensive alternatives i guess- and i really don't get adding oil to a starch???
i hate it when i receive any fabrics that have a perfumy stench to them- firs thing i have to do is wash them to get rid of it before i can do anything with them.
