Once I tried spray basting I never looked back. Just the thought of pinning a whole quilt again , just turns me OFF. My mom is always reluctant to try new things. I think because of the cost and reluctant to change, but gave her a can. Yep I had to really push her , as she is prone to saving it for "someday". Now its the first thing she will buy with her JoAnn's coupon.
I guess I am saying just try the spray , your knees will thank -you. Just remember a little goes a long way.
