When I make my paper piecings I print my pattern off and since I don't have a light box or anything like that so I can trace my pattern. What I do is I take a pencil and colour the back of the pattern with it, then I position my pattern on the cardstock and trace over the pattern on the right side of the pattern, when I am done I have a perfect pencil replica of the pattern on my cardstock. No muss no fuss.
