The High Museum's October 21 Access for All Centennial Celebration includes free admission, gallery conversations, and drop-in art making. A Postcards from the High workshop uses collage and image transfer; the museum lists sessions from 10 a.m. to noon and 2 to 4 p.m.

A 1 p.m. HIGHlights tour offers another way to explore the collection. It is a different event from Sunday's centennial block party and an opportunity to visit without normal admission cost. Action: register through the official page and plan around the art-making sessions.
