I use regular printer paper because I copy for free or purchase most of my paper piecing patterns off the internet. I have also been told, but never tried it, that onion skin works well in printers and is easy to sew on. Sometimes I buy 8 1/2 by 11 paper tablets and use that because it is cheaper than 20 lb. printer paper. Whatever you use, have fun. Paper piecing is my favorite. And you have started out beautifully.
