Christy Caine designed these stickers and they deserve a much wider audience.
Go read her blog and why she designed these stickers. Go buy her stickers. Display them proudly.
This one is my personal favorite because it is so very clear and easy to distinguish from a distance:
This one also gets the point across for those who wish to be a bit more discrete:
I say we need to dispense with discretion and be blatant about it. We need to be in control of our bodies. If we cannot make decisions about what happens to us and our bodies, what health care we receive, how we take care of ourselves, and accept the consequences of our actions, then we are not free. If the consequence of taking control of our health and our bodies is imprisonment, then we aren't free.
These are just stickers, but they send a powerful message.
