House Unity Squares

I am not sure how other people select the colors they to put next into their memory blanket. I sort of try to make sure that I am distributing the colors fairly evenly, but it isn't a particularly strict system.


For this though I will make an exception:
[For those of you less familiar, the center squares are in the Hogwarts house colors. From top going clockwise there is: Hufflepuff (black and yellow), Ravenclaw (blue and bronze/brown), Gryffindor (red and gold) and Slytherin (green and silver/grey).]
