I have given retiring chapter advisors a pendant made of three different colored pearls arranged horizontally to symbolize how their participation in AOII has changed with their past, present, and future.
Emporium also has historical badges in a variety of price ranges. Ask for Shelley.
If I were a retiring chapter advisor, I would LOVE to get the alternating ruby and pearl lavalier (Christin and I adore this lavalier....just in case anyone has missed out on this point). I think this lavalier in goldgloss is around $88.
