Making a plan translucent

Hello. I have an E-Hawk 1500, and have built the stbd wing panel, using the plan as a guide. How do i make the port wing, as there is no drawing supplied. Do i have to make the drawing translucent somehow, or does it not matter, as the spars and ribs are lasercut?  Regards.

Edit: I guess it does matter, to ensure the overall shape is correct, the top and bottom sheet is very narrow at the trailing edge, and could go "off profile" quite easily.

Also, i'd imagine it would take several prints to get the scale to match.

I'm guessing no one has a way of making a paper plan translucent? I was thinking WD-40, or linseed oil, but would ideally like to avoid the oilyness. Some kind of wax perhaps? Surely there's a tried and trusted way of doing such a simple thing?

A print or photographic shop should be able to scan it in & produce a mirror image print out.

Old Trick, which I have used many times when I was using/building Balsa and tissue models years ago. Get cookery Grease Proof Paper. It is fairly translucent and carefully trace the plan parts through it.
 

Thanks Eric, I tried to paste a photo and yes.. gobledegook. I thought I had deleted it tho'.
