I use my own printer paper as well...something that helps if you have trouble pulling the pieces off is either folding along the lines before you begin sewing, or running it through the sewing machine without any thread to perforate the lines so they tear off easier. But in my experience, if you're dropping your stitch down to 18 stiches or so per inch, those teensy stitches will do the job on their own and make the paper pretty easy to tear off.
