I am currently working on a Christmas tree skirt that is almost entirely paper pieced. This is really my first project paper piecing, but I do have the basics down. My question is this. Is there any way to use my time a little more efficiently? Right now this is how I'm working. I put the next fabric piece into place, sew, press, fold and trim the excess. I'm wondering if it wouldn't be better to have a lot of units ready, sew them all, then press them all, then trim them all, instead of doing each one at a time. Or does it not make a difference in the long run?
