Como uma improvisação musical, mas feita de traços, cores e gestos
Jam Drawing Session is an open, relaxed drawing jam, like a musical improvisation made of lines, colors, and gestures. It is not a class: no mandatory technique, no right or wrong; everyone is invited to experiment and create together.
