I have 2" think foam insulation boards that I bought at Home Depot, was able to talk the guys into cutting it in half for me so I ended up with 4 pieces that are each 2 feet wide. I then used Super 77 spray glue and covered each piece with white flannel.....When I am piecing my quilt the individual blocks stick to the flannel, when I start to sew strips I use pins. Because each piece is 2 foot wide I can put up exactly how many I need for the width of the quilt I am making.....I have not used mine for spray basting....but don't see why it wouldn't work, perhaps hang a sheet of it and on the floor. I have always done by spray basting on my dinning room table with a sheet....and have not really 'noticed spray all over the room'.....
