This tip doesn't have a thing at all to do with quilting. When the temps are low enough that your windshield washer fluid hoses are frozen, I keep a little spray bottle of it in the house and take it to the car with me. When I'm parked, I can spray down the windshield, use my wipers and my windshield is clean.
Forgot all about it until I needed it today. Sure came in handy.
