Gentlemen,

I'm interested in doing some custom cards dealing with the Finnish Air Force (Suomen Ilmavoimat) and both the Winter War of '39-'40 and the Continuation War of '41-'44.

So, any tips, hints, or methods out there for doing custom cards before I start?

I'm not really a good tip give but I have made some of my own customs and currently working on one right now
