Here are some flags I made for Nation States.
Here are some I made for another project.

Obviously, no charge. I just like making flags. I might take a while to make one if requested, however, due to school work. Also please tell me about any specific colours to use / avoid, or symbols to use. Custom symbols are way easier to add if you give me a file or a link to them.
