Easiest for tracing is thin masking tape and a pencil. Not too soft maybe 2B or harder.

What about using very thin solder? You can flatten it using i.e. a vice, it's easy to bend and shiny silver.
There is a little clamp where you can hide the ends.
Still a thrill to attach, but hey, if there is someone able to, it's you

Seeing Jans very good advice - what about:
-tracing with masking tape and pencil
-put tape on bare metal....better something a bit thicker
-cut out with parallel cutter:

That should do the trick......

CORRECTION!

First thoughts are always best.

This took me ten minutes including pics and upload with smd solder:

Hi Pit,

Unfortunately I don't know where I bought it. Some common shop I guess.

I've searched a bit yesterday.
Mine has 0,5mm thickness, no name on it.
Thinnest I found online was 0,2mm.

(Sorry guys, I only searched for German shops)
0,3mm quite cheap 2,70€ : Westfalia

Found 0,2mm at Reichelt but just a big pack for 28€ something .
Don't know anything about this shop but it offers 0,23mm 2 Meters for 4,50 €:
?????

If you search for "smd lötdraht" on e**y you will get a variety of different solder even in different colours.
Eeeeb****y
And one find for U.K.
SMD tin solder

Yesterday I flatten it with a battery (AA or something else which is round) until it was around 0,2mm thick and 0,7mm width.
It's very easy to bend, therefore a bit fragile too.
You can polish it to high silver shine or sand it to alloy like look.

But one thing is uncertain for me.
Most of modern solder have this fluid inside. I don't know if that can harm anything. I guess some lacquer on top can't be wrong.
Even to keep silver shine.

It's fun to play with (take care to buy lead free solder).

Hope that helps.

Cheers,

Knacki
