Some of the sprays are best used outdoors or with excellent ventilation. I think it's the 505 that people say doesn't have that strong toxic odor. It's only while spraying that there is a problem. Once the quilt is sandwiched, I haven't noticed any residual odor. The basting adhesive is water-soluble so is gone with the first washing of the quilt.

One way to use it is on a large quilt is to spread out a sheet first on the ground. That catches any overspray and can be just thrown in the wash. On a smaller quilt, you can just tape the backing to a kitchen island and insert old newspaper around the edges to catch overspray.

Basting spray is good to use because it's fast -- takes much less time than other basting methods -- and easy. For someone like me who has a bad back and bad knnes, it is a lifesaver. Also, I once ruined an expensive walking foot when it got hung up on a safety pin in my quilt; would have saved me money if I had spray-basted that quilt!
