My goddaughter joined Theta 2 years ago. Had the same flower situation and asked her what I should send. She said to send Theta swag! Said she’d rather have apparel than flowers that would be gone in a week.
Amazon has many pages of cute Theta items and if you’re a Prime member, lots to choose from with free shipping directly to her campus address.
I found several jewelry items in black and gold at
www.shoplc.com It’s an auction website, as well as a retail site, where I purchased probably 8 items for about $60! She is well accessorized for chapter dinners!
Couldn’t find a “kite” in my search (so that’s why I searched for “black” and “gold”), but if your sorority has a symbol/flower that is trendy in fashion (owl, anchor, angel, dolphin, rose, etc.), you can get nice jewelry pieces at bargain prices. I’ve loaded up on owl jewelry as I give the UCLA chapter President, Recruitment Chair and my Panhellenic Rep. owl jewelry right before Recruitment starts. It can be a good conversation starter.
