I spray baste my larger quilts on my bed. I have trouble with my back so spraying on the floor/ground does not work for me. I remove my duvet and cover the bed with a clean, old drop cloth. Then I cover that with another thick cloth. I lay my backing down and smooth it out and use T-pins to secure it tautly (is that word?). Then I lay the batting down. I then roll back half of the batting and spray. Smooth it down, then roll the top half back and spray then smooth that part down. I let that sit for a few minutes then I repeat with the top. All of the layers are well adhered and wrinkle free.

I use 505 exclusively. I do not have a problem with overspray at all. I do open a window (if it is a windless day). I think that the problems with overspray come in from being too far away from the object. Also, I make sure that I have a decent sized border of protective covering under the quilt. I would definitely suggest you try it on a bed. It is so much easier. I am actually looking for a nice large piece of fleece backed vinyl to use. Then I would only have to cover with that layer rather than the two.

I use this method in my hall.

I really like the link you gave, Bev! I do have a design wall and will have to try this. Right now I use my chest freezer that is on our covered back porch. I have an old moving pad down first then an old sheet. It has worked pretty good. But, I will try the design wall technique, too. Thanks!

:) Your welcome. I really like it 'cause I can do it by myself, in half the time.

Thx 4 all the comments!!

I used the back of the shower for a wall hanging. Worked great.
