okay, ladies. i see you keep talking about using spray basting. when you use it, don't you just have to spray it and use it right now? or the hold lets loose? and get it quilted right away? 6 yrs or so ago, that is what i found. or was i doing it wrong. i was still working, and would try to lay it out, and then quilt some the next day, then want to do some the 3rd day. and MY spray basting didn't seem to hold. am i mis remembering? or was i just doing it wrong?
