To be fair the Maryland flag is easily one of the best state flags. It fails the "Could you easily draw it from memory" test but the design and color scheme more than makes up for that. I'd put it everywhere too.
I remember spending a day in fourth grade during Maryland history reproducing the flag on construction paper. (Admittedly that was many years ago; my children apparently didn’t get this exercise.) The Crossland parts are pretty easy; the Calvert parts are a little harder. The tricky parts are getting the number of pales correct, and coloring in all the countercharges correctly (i.e. where the red goes vs. white, and where the black goes vs. yellow).
