This is an excellent question. (I've been thinking I need patches on my non-St. Paul corduroy jacket to make my own special jacket that is special or something.)

Someone gave me one, so they exist! Let me see if they know the source!

I can think of a recent T-shirt design that would make a great patch

there’s plenty of them about online (etsy, ebay, etc.), but the provenance about whether the proceeds actually go to community aid or if they’re just crisis profiteering is pretty iffy on most of them

I've seen some online... Minacqua brewing maybe

Need one for a GS vest 👀
