Are you thinking that spray basting with 505 would be too expensive? I haven't figured out the exact cost per quilt of using 505, but I know it's not enough to keep me from using it. I can't imagine doing all that extra work to baste a large quilt when I can easily do it with 505. It does not lose its stickiness over time; only when the quilt is washed. I buy it online and estimate it costs $10 or less per queen-size quilt to use it.
