Spray basting is the way to go for me. I go to my church and lay my quilt on the tables there and spray baste. My first quilt (other than tying a comforter) was 90 something x 106 or something like that . I spray basted it and then quilted it with a small hand held hoop. I figure that the most important thing is to get the quilt centered and then work out from there, smoothing as you go. At least this is the way that I did it. Do any of you do it that way too?
