Please do me a big, big favor and don't use quilting basting spray in the house at all, to say nothing of overhead! If you read the warnings on the label they're very specific about how to use the sprays. Breathing in those fumes is much like breathing in spray paint or dry cleaning fluid fumes. I put whatever I want to spray down on my deck (waiting for a non-windy time) on top of a sheet and spray cautiously, trying hard not to breathe in any of the mist, then take the piece I've sprayed into the house. When I'm done I toss the sheet right into the washer. I think it's dangerous stuff and should be used exactly as the manufacturer directs.
