What an interesting border design, KalamaQ!
I am also working on QSTs. I finished the clue 6 last night and hope to finish clue 7s today. (I don't mind QSTs, since they come out the right size, unlike those pesky tri-recs units).
I've decided to change the outer area of the quilt, and just put neutral 4-patches in between the protruding magenta star points. I'm considering a border idea using QSTs, but that would mean making an additional 108 of them. I'd hate to make them and then decide it was a bad idea, lol.
