Recently I made arrangements with my brother to sell items I'm making in my spare time. It might seem laughable that a middle-aged man is crocheting, but frankly, it's a way to support myself while in prison. It also occupies my spare time with something useful. I'm just starting so there aren't many items listed yet, but check it out:

Be sure to check back regularly for new items, and fee free to share this link on Facebook or Twitter if you like it. I hope to add other things that other prisoners have made too.
