I have done several baby quilts, approx. 54 x70 or there about with the birthing method, as I don't especially like binding, although I do on larger quilts. I would suggest that after turning the quilt RSO, I would carefully PRESS the quilt top, then pin baste with safety pins, this should eliminate bunching, creeping, etc. After quilting the top, I would sew 1/2" away from the sides, as this gives the impression of binding without that process. I tend to drive my best friend when I do quilts this way, but I have never mastered her method of pulling the backing over the quilt to make a binding either. I say go for it as I have had good luck with this method, as long as it's no larger than a lap size quilt.
