Just before Christmas German artist Michael Pendry installed Les Colombes (The Doves) at the Washington National Gallery. The exhibit consists of thousands of origami doves as a message of hope for 2021.
The National Gallery is closed right now because of COVID. But you can register to receive an email announcement for when it is open again by clicking here.
Want to make your own origami hanging sculpture? Here is a PDF of artist Pendry's instructions. Pendry recommends that you write a message of hope on the paper before folding it. You then can hang it or give it to someone.
