I find pin basting much easier/more reliable than spray basting if I'm doing something on my domestic vs. my longarm. I roll the quilt top, quilt back, and batting up on 1x2 furring strips that are longer than the quilt is wide, then layer and unroll all three together and pin baste (I use the now-discontinued Kwik-klip tool and Paula Jean pin covers).
If you Google "pool noodle quilt basting" you'll see what I do except they use pool noodles. I line my ironing board up next to my cutting table to make a long surface. I can stand and work at a comfortable height and get all 3 layers nice and smooth.
