When I take my 108 inch backing fabric off the bolt to measure, it has creases where it has been folded and is often wrinkled in places. It is so large to try and iron. The girl that showed me how to load my quilt in the long arm frame told me to spray the backing with water and the creases and wrinkles will come out. What method do you use to get the wrinkles out or do you use the spray trick? I'm still a newbie at this long arming stuff. I'm a hand quilter and use my hoops to stretch the wrinkles out. Help!!!
