From the link I gave, I think I'd really like color #13 - Gray Damask, with black thread saying 'Ms Becki'. My uniform shirt for most of the week is green and white, but I currently have two dress down days each week, so then I have no idea what I'm wearing my lanyard with ;)
I've now been serving meals at the school for a little longer than a year, and I doubt I'll leave anytime soon. A personalized lanyard (and maybe some seasonal aprons with at least two big pockets?) would really spice things up for me.
