Yup...lots of letters and wear them when approriate
My car license plates are vanity plates that say "Phi Mu" (a gift from Mr. Sageofages when I bought the car).
Key ring, checkbook cover AND checks, alumna decal in window, and I carry my needlecrafts (crochet, knit, cross stitch, or quilt) in a great pink Phi Mu bag. They are all great conversation starts....
"you are a Phi Mu? Wow...I *was* an XYZ in college" I use it to remind them membership does not stop when you leave college

and encourage them to get involved in a fun way with their alum organization.
