Always happy to see you join a thread, Honey.
I had no idea ADPi pins are now mini. I'm curious about why that was done. We actually don't have minis anymore. I think they were common before they were standardized and we had an official jeweler.
I have most of my KD pins displayed in glass trays. Other items like vintage KD rings and pendants are in a glass case on velvet jeweler's displays. I'll admit I'm a little excessive about it.
How about doing a shadow box for your pins? Maybe with some nice azure blue fabric as the backdrop? You could hang it near your framed Alpha Delta Pi creed. (Of course, I don't know for sure that you have one but I'd put money on it.
) I'm considering moving mine into a shadow box so I can more easily see them.
ETA: Correct me if I'm wrong but it seems like the newer ADPi pins I've seen have the clasped hands raised. Is this a new thing, an old thing that's come back???
