A neatly written note posted in all locations that it's appropriate to post such things:
"Seeking a mentor in the art of glassblowing, the basics of which I am strongly grounded (journeyman rank). Also seeking a mentor in the art of ceramics and pottery, the basics of which I am familiar (apprentice rank). Able to offer a small sum of coin per lesson or a larger sum after fulfilling my apprenticeship.
I can most easily be found at The Lonely Inn.
