Personally I'd rather just buy the starch spray than mess with making my own. The only reason I use the vodka/water mix instead of Mary Ellen's is because my dd has several allergies and the company that makes Mary Ellen's won't tell me if any of the ingredients are ones she is allergic to. When companies refuse to disclose information like that it makes me not want to do business with them at all (there are entire food companies we don't use because of this).
