Old Paraphanelia

Here's a question for anyone: What do you do with your greek paraphanelia that is old or worn out? I have items like this and I feel it's inappropriate for me to throw them in the trash (it would feel like I am throwing out my letters). I don't want to donate them to Goodwill because then a non-member can end up wearing them. If it was a matter of an item being too big/too small, I would just give it to a sister that fits it, but what do you do with worn out t-shirts, sweatshirts, etc.?
