If I can't finish basting a larger quilt, or sometimes even a small quilt, if I'm dealing with something that needs my immediate attention, I have left it overnight. I seriously doubt that leaving it for a night or two would be a problem. I just noticed that you live in Australia? Where in Australia? I ask because my daughter moved to Sydney to be with her new husband about a year ago and she really likes it there and just started to work at the Sydney Airport. Australia is one place my DH and I have always wanted to visit. We'll see if we can afford the plane fare to go there some day.
