I have been quilting many years and I do use spray basting...I have never had a problem..I used it on a Queen size in there was no problem...but..I also have a huge cabinet making table out in our garage that lets me spray baste without a problem on size of quilt...I have attached pictures that I put up on Shutterfly and I hope this helps..

When you start spray basting its hard to go back...you have to have the area to work in..open area with air...but not blowing on you..while you work...I just sprayed on yesterday...it has to be above 50 deg's to spray ...hope this helps...Nanda in Texas

Think I might be able to figure this out...how to post the pictures??? ha ha..here we go.....sorry I tried but failed...hope to figure this out..it might be easier for me to just email you the pictures...how crazy!!

Go to you tube and type this in the search and look at this tutorial, Patsy Thompson ( I believe that is her name) makes it seem very possible...
