Why don't you try Elmer's washable school glue? I think you would lay out your quilt like spray basting. I just put a thin drizzle of the glue in a kind of grid about 4 inches apart onto the batting. Then flip over and do other side. I let dry overnight but it can be ironed to dry faster. Does. Not gum up needle when dry and always washes out. Very inexpensive and no fumes. Some people dilute it and paint it on the entire surface. I have never found that necessary - I'm 30 plus quilts in and have never had a wrinkle.
