I thought I had mentioned this before, but apparently not. I first heard about this program when one of the local yarn stores was trying to help garner votes for a donation to support the program. The program at the time was teaching prisoners to knit and having them make trauma buddies (stuffed items trauma workers could offer to a kid at a trauma scene to try and help calm them down). This article states that the program has expanded beyond that and now even has a waiting list.
I'm so happy to hear that this program has had such success. And hopefully, some similar programs will get started elsewhere.
