This guy has a great writeup on how much he loves flags:
Basically, I’m interested in flags and politics, so I see the EU flag displayed officially in Germany, France, and Italy (these three are particularly distinct) quite often in the news etc.
As can be seen above, Italy always uses a very heavy material for its flags, and the stars appear to be embroidered rather than printed or sewn on. This reminds me of Italian opulence and the baroque style. They are decadent, and more ornate than necessary.
In France, the flags are always perfectly neat. They hang in a flat, straight triangle. Almost always, four stars of the EU flag are visible (and they’re printed). There’s sometimes a bit of a sheen to them, but they are not glossy, and they are never translucent. Overall, I see them as characterised by simplicity, elegance, and style. Example.
German flags are (what else?) functional. They are not hung with the same care as in France, so some of the details (stars for the EU flag) can be obscured, and there are a lot of long rumples (but they’re not folded in on themselves like in France). The details are also printed, not embroidered or attached. They are very shiny, and look to me to be durable. Like the Italian ones, they will last a long time (indoors), but they also look like they could be very easily cleaned with a damp cloth, and are not overly extravagant. Example.
The US also has a very specific type of EU flag it displays. It’s not stylistic preference, it’s just objectively incorrect. The stars they put on the EU flag are far too small (as small as the ones on the US flag). It makes US-hosted press conferences look rather amateurish in my opinion. Example.
