Hello Zultra!
If you are interested in making a good flag, then I recommend you watch this for some pointers. You could skim it since it is eighteen minutes. I think the best advice to remember is that it should be simple, and a child should be capable of remembering and replicating it. Good luck, and may you prosper in your future endeavors!
