I haven't tried glue yet but I am a big fan of spray baste. Takes awhile to get the right distance and the right amount of spray.
Don't get rid of your pins though, they will come up for use from time to time. Recently I've been dealing with some fabrics that weren't easy to tell what side was "right" and in this project it mattered to me. What I found was the easiest way to deal with them was to not fold strips when I cut them, but to layout everything right side up, cut my pieces into groups of 6-ish and pinned them together with the safety pin, right side up and the pin was on top as a handle. Got out my box of safety pins and my life became much better. In my case the fabrics were hand dyed but I've had a hard time with white on whites and fabrics with subtle shines or other differences.
