I made a Green and White Hunter's star ;-)
I think you have 2 options, something that's overtly U of M, like the block letter or use the official collegiate fabric with U of M printed all over it.
OR look for a two color quilt pattern that you like, like a Hunter's Star and use Maize & Blue.

You can use the print on the back.
Country Stitches had fabrics for both colleges last time I was there, sometimes JoAnn's has it or you can order it on line.
