Other options are open; perhaps choosing three colors, or combining marker with pencil and a color wash.
Please post on the morning of April 17th, by:
(1) posting to this blog
(2) emailing to our mailing list, or
(3) posting in our Facebook group
As always, this challenge is optional, and you can be as strict to the subject or as loose as you like. Your participation is welcome whether you choose this challenge or not-- just make sure to work from life and to include contextual information, so it stays in the realm of urban sketching!
And Peggy has again graciously offered to host a zoom meetup that afternoon. (Login details will follow on the mailing list, closer to the date.)
