The Portraits of Hope 24-hour Paint-A-Thon is open to anyone who is 8 years old or over. Sessions are 2 hours and completely free. All skill levels welcome. Templates and step-by-step guidance are provided, so anyone can create something beautiful.

Every panel painted becomes part of America Shines on The National Mall, a national initiative honoring the U.S. 250th anniversary, with a 4-week exhibition at the Lincoln Memorial Reflecting Pool later this year.  They expect 20,000 participants across all 50 states.

Free, but you need to reserve your slot. It runs from 10 am on Saturday to 10 am on Sunday.
