I always use sizing, never starch, and its only $1.00 a can at Walmart!!

Candace, I applaud your concern.
I have many allergies and anything with a smell to it (even if it's a nice one) can cause a reaction in me. Therefore I use a face mask when I spray basting (love that stuff) even though I use one with "no smell." I also have an air vent in my quilting room to take out fumes.
However, I wonder if you are thinking of chloroflurocarbons that are bad for the ozone? They were banned 30 years ago.
