I was leary of it at first. Then I bought a can to use for the large quilted bag I was making for my son's girlfriend. After using it I thought...what was I afraid of. I have Dritz and I don't find much of an odor at all when using it. I don't wear a mask...have them for when I make soaps using lye. I use an old bedsheet to protect wherever I am spraying.
When I made my large round Christmas table topper I also used it. It makes your project go so much quicker than having to stand there pinning the layers together. I finished piecing my table runner yesterday and have my batting and backing fabric cut and ready to spray so I can start the quilting. Oh...on my table topper..the middle circle I placed 4 things that I wanted to do hand applique. The girl at Joann's told me to use the basting spray on them to hold them in place. They were cut out of felt. Used it and it worked perfect for that too.
