Paper piecing is a great method for very intricate blocks or those with really fine points. It does take some time to get the hang of the process. I, too, just use copy paper because it's what's handy. Definitely reduce your stitch length for ease of taking off paper - which you dont' do until the block is complete. Does make for great difficulty in fixing booboos, though! I've heard others use vellum paper as well. And as someone else mentioned, definitely cut your fabric pieces way oversize until you really get the hang of the process. For first section, place wrong side of fabric to back of paper making sure all lines are covered by at least 1/2". For section 2, again, making sure you have at least 1/2 of fabric all the way around for that section, put that piece of fabric right side to right side of first piece of fabric, best (in my opinion) to line up edges with section 1 fabric. Sew on line between sections 1 and 2. Fold back paper to sewing line, trim that seam to 1/4". Press the daylights out of it making sure it's really, really, flat. Proceed to section 3, etc. Good luck. It can be a very tedious process but one that makes some incredible blocks/quilts.
