After basting my first quilt with school glue, I never looked back at spray basting or pins.....it holds wonderful until the quilting is done....then all washes out!.....if you use enough glue (and either iron dry or air dry before quilting), you can start quilting anywhere because the fabrics will not shift or pucker.....there are several tutorials here on the board.....I don't know what pattern you have for the top, but a couple stabilizing rows of quilting will make you feel better and give you some guidelines for any fmq.....diagonal lines or cross hatching is very easy for baby quilts (just use a long straight edge and a washable marker).....
