How to make model in format (A2) when all you have is (A3) ?

Hey, here is the question.

My local printing offices can only offer me prints to size A3 (paper format).

So when i design my models, i am bound to this size ? (A3)

Or are there any techniques to manipulate with A3 prints to make models bigger.

Like, can you glue two A3 formats together or something , so you can make bigger model in the end ?


I hope you understand me, i am very new to paper modeling. I am makeing
my first model right now. I made plans so they fit A3 format, but i am asking , for my future projects.

Thank you very much, i like your works very much.
