I think it will be difficult to hand quilt after spray basting a quilt. I also hand quilt and have a long arm. When i want to hand quilt something, I put it on the long arm and baste it there. Then I can hand quilt it and take out the basting stitches. Is there a long arm quilter who could do that for you? The glue basting would make it to stiff to put the needle thru.
