I have back and knee problems, so can't bend over for long periods of time or get on my knees, so I spray baste my wallhangings on my design wall. I cover the wall with a sheet, then pin the backing on the design wall. I spray with the adhesive, then place the batting on top of the backing and pin the batting to the wall. Smooth everything down, then spray the batting and place the top on the batting and pin the top to the wall. Once again, smooth everything down. I haven't tried this with a full-size quilt yet, but for wallhangings, table runners, etc., it works great. Also, are you FMQ with a hopping foot or quilting with a walking foot. I've never had a problem with tucks when I use my walking foot.
