I've tried paper piecing a few times, with limited success. There are some people that can whip anything out in a heartbeat using the method and there are others that just can't.
One thing that I just could not get over was the amount of fabric that was wasted. I'm not a miser, but to me, I value how much we spend on fabric for our quilts and I moved away from paper piecing. I just can't afford wasting that much fabric when I could easily just measure twice, cut once and make sure my seams are 1/4". If I make a mistake, I make a mistake and reach for my seam ripper.
