I remember reading a thread with some general craft ideas that might help out a bit.
Anyway, my "family line" adopted teal as our family color. If your chapter/family does something similar you could paint the frame that color or use it as an accent.
PAINT PENS, PAINT PENS, PAINT PENS!
Maybe use your sorority's open symbols? Someone in my chapter made a "Big Sis: _______, Little Sis: ________" mug at some point.
Several crafty blogs might also have some non-Greek projects that could give some inspiration.
