Amazon.com: Sulky 4.23-Ounce Temporary Spray Adhesive : Arts, Crafts & Sewing

This is a good product for spray basting quilt tops - pieced, appliquéd, or wholecloth - for hand or machine quilting. I have tried most of the popular brands but keep coming back to this one for good adhesion with not a lot of product - a thin layer is all that is needed, and no lingering odor. It seems higher priced than others, but it is very concentrated and has a lower pressure spray so it doesn't blast all over (garage, plants, or deck). As with most brands, it helps to spray the fabric and not the batting. I was not aware, until recently, that there is not an urgent need to immediately layer the sandwich - one could spray outside (advised with all sprays) and then bring the top indoors to assemble the layers. Do take note, though, that Sulky KK 2000 was designed to disappear over a short time (a couple of days or so), so this is not a brand to spray and leave your quilt for quilting "sometime" or you might have to spray again. I, personally, like this quality as it provides motivation to get the quilting done. Only one caveat: although it is labeled "Safe," I still recommend wearing a mask, use eye protection and spray in a well-ventilated space (outdoors is best).
