I looked at the crest for the country itself. It's similar, but I simplified it and did my own twist on it. I made the same pattern as the flag with the design bolder separating the white and maroon. The inner circle now has crossing arabic swards, and a dhow because of the ports in Qatar.
I really could do anything I wanted to with the jerseys. I wanted to do something like the flag, so I ran a sash running down the left side with the pattern ending the white band. It's pretty simple as a whole, I just love that color.
