Honor Martin Luther King Day by creating your own protest signs at the Old Stone House! Whether you’re marching in DC, NYC or just want to speak your mind, we’ll have posterboard, pens, markers, and paints. Please bring any other supplies you'd like to share, and B.Y.O.P.B. (bring your own poster board,) if you have any available! If you'd like to bring foam core for your poster, that's fine too. It's a tougher material, but it's not biodegradable.
