You will be surprised to find out that the comets and mines were all 2" or under. I am not kidding here. Richard Bland of Spectrum Pyrotechnics has these things down perfect.

He also has the purest colors you can produce using chemicals not often saught after due to there complexity in use. You are correct in your assumption that the inner petal stars reside just inside the outer petal stars.
