Tracing my vintage pattern

My lovely vintage patterns arrived from What-I-Found, and they are perfect. Both uncut, none of the pieces are missing and both have the instructions. So now, I have the fun job of tracing them (as I would like to conserve them as they are). I always find tracing a pain, but with vintage it is even harder! When I am tracing from, say, Burda magazine I just staple the pages together to stop them moving around but I can't really do that this time. I have looked at pattern weights before but they seem like an unnecessary (big) expense. So I am using the wish and hope method, going ahead and wishing and hoping that pieces don't move to much and cause to much distortion.

Wish me luck!
