I spray baste all of my quilts on my bed. I use an old fitted sheet that I put over my bed and then on top of that I have an old duvet cover that I don't use anymore. Then I take my well starched and pressed backing and lay it down. Using T-pins I lightly secure the backing just to give it a little tension to ensure that there are no puckers and then I lay my batting down and then my top. Unless it is a windy day I open the window and start. I have no problems with overspray or any glue or anything getting on the furniture or floor or anywhere it shouldn't. Since I began spray basting I have stopped dreading quilting. I've not had any puckers or wrinkles and no pain in my back or knees.
