I just completed my first scrappy quilt and used the paper bag method. It was a stretch for me as I usually agonize over color placement etc. The only time I didn't honor the bag method was if I pulled out 2 pieces that were the same (2 dark blues, or 2 reds, etc) that were supposed to go next to each other. In that case, I'd toss one back in and grab another. It worked great and I'm very happy with the outcome.
