It can difficult to make a Latvian flag without accidentally making an Austrian flag. For beginners, it's possible to miss the tricks of making different size shapes and if someone tries to make a Latvian flag, chances are they'll mistakenly make an Austrian flag by having a solid white stripe down a red banner, therefore making the white bar too thick as opposed to the Latvian flags' thin white bar.

I'm fanatical about European flags and always try to make the flags as accurate as physically possible by Minecraft limitations.
