hmmm, i always safety pin my quilts, and that works really well for me, but it is very back-breaking doing this. I don't think i would want to use a spray baste myself, not comfortable of the idea of the chemicals and fumes, over-spray, mess, etc...i do like Izy'a idea of using a micro gun, i might try that someday, but yeah, basting isn't fun lol, especially in a small space :)
