hi there
i have never tried to build a paper model, but when i was younger, i made a loft of models, like tanks, aircraft mostly wwll. so i have a little experience in model making.
about a year ago, i bought a model from "Wish" and it's the GMP bismark 128.
i thought it was a small model, easy to put together, well it's not.
but anyway i'll start with the hull, and what thickness of karton should i use
1 or 2 mm, i have both ?
secondly, is their any instructions for this model ?, i only have some drawings.
any comment will be helpfull.

best regards
