What I have tried is carbon paper reversed so the black is facing up but laid against the pattern and taped down with scotch tape. Then lay a bit of tissue paper on top of that and tape it down. Then if you gently rub the whole patter with a crayon or other round dowel rod you can get a transfer onto the tissue paper. Then I copy that on a copy machine to more durable paper. You can use regular copy paper to, but I find tissue paper is more flexible and will follow the curve better.
