Can't really help you there. I use both the bent safety pins or basting spray. When I don't have enough space, I find a place where I can baste it. Many LQS offer their class space to do that.
I can't send my quilts out to be quilted by someone else because they would not be "my" quilts any longer. So I practice, practice, practice to get better at that FMQ. I wish I could send some out coz I would get more done. So if you feel comfortable with that, good luck. I know that Charisma from the QB is a fabulous quilter. Maybe someone else can point you to a local quilter.
