I prop one or two sheets of thin plywood against our fence and use one or both as a wall for spraying. I use push pins to hold the backing on the plywood. I can always find a sunny day even in winter to spray baste, it doesn't take long. DH bought me two thin sheets of plywood just for this purpose and attached a leather strip on one end of each for handles. They are easy to store in the garage and light enough for me to pull them out.

An instructor told us to hold the can at a 90* angle prevent overspray. Since I started holding the
can like that I have not had a problem.

I have used the 505 spray and haven't had a problem with overspray.....but I did use Sullivans spray just once and it was a disaster....worked like super glue. Yup, glued my fingers together and had to use fingernail polish remover to un-stick myself.

I spray baste on an old table. I spray the batting, somewhere I read that that was recommended. I spray baste from the center out.

I used the spray baste on a small project at the kitchen table once! I had used what I thought was plenty of newspapers that was covered everything but when I was done I had the over spray all over my DH cell phone. We tried everything to get that off and ended up at the cell phone store where the replaced the face cover of the phone. So I do not use sprays at all any more inside. I really like to use the tape that is used for hems. I start in the middle and work out. I did this on a queen size quilt and it turned out great.

Sharon-OH - and do you use your iron to fuse the tape?
