Are there enough flags?
Tried creating a set of Q-overlaid country flags and they just looked terrible and I bailed. Think the only way to do country flags is to create them 20x16 rather than shrinking a set of good-looking flags.
Easy to do more solid colors though if more are needed. Tried some diagonals and they too looked horrible at 20x16 size. Maybe anon just lacks the skillz, kek.
