What’s the last set?

I can’t find the last set, if anyone does (I’m sure you can). Please let me know.


  1. says

    red shaded single squiggle
    red solid double ovals
    red empty triple diamonds

    Tar dar!

    Bit late though. I did that one in about nine minutes, but I couldn’t remember the set by the time I got to read your entry, and then it took me days of puzzling. :)
