Hi, welcome to Greekchat!!
Here are some ideas that my chapter did when I was Spirit Chair.
Violet Box-
Basically is a plastic box like a inexpensive fish aquarium that is decorated. You put violet notes (little notes of support or encouragement) to a sister(s) that you read outloud to the chapter at the end of chapter meetings. For example, To Sherra, hope you have a good week, thanks for helping me with painting posters Pi love Ally. Something short and sweet.
And any sister can contribute violet notes.
an Alphie (a stuffed animal lion) that you give to a sister that had a bad week, maybe she's had a cold or was sick, or stressed out about midterms, or broke up with her bf, etc. It's a reminder that her sisters care about her.
She would have the Alphie for that week, then next chapter meeting, she would give it to a sister she thought needed it.
SunShine Pail-
It's a basket or pail that is decorated that is filled with goodies like candy, cookies, ADPi trinkets (like keychain, handmade gifts, etc), travel sized lotions, or whatever else you want, maybe keep it around $5-10. You give it to a sister you think did a good job doing a task, maybe she was the chair of a fundraiser and it turned out great. Then the sister you gave it to in turn next week fills the basket/pail with goodies and gives it to a sister she thinks did a good job with something. And so on
Learn a new ADPi song at the end of each chapter meeting, that ways it gets everyone involved and it would be fun.
Hope this helps.
Pi love, Ally
