As the unofficial "aunts" of the Lambda Pi chapter (our "big" was Susan Bermann, NVP of Membership
), my SAI sister and I made little black pillows that had SAI (the greek letters) sewn on in ribbon. They loved them on installation day. We had also made folders for them to keep papers in during the process and little snacks and treats here and there.
My big made a frame for me that had random SAI lines on it (from the Chorale, Symphony, etc). She also got me a tote bag that was embroidered with the letters, and a binder with our family tree (now hazing
) on it.
