The Dedham Square Artist Guild has put out a challenge for area artists to make waves. They may submit two pieces to the guild on the theme of “waking waves” – whether on the water, to a friend, or to the status quo. The pieces, with a $25 entry fee and signed entry form, are due to the guild by Sept. 10. Entries can be sent to Dedham Square Artist Guild, 553 High St., Dedham, MA 02026 or to firstname.lastname@example.org. The exhibition will be at Dedham Community Theatre and run from Sept. 26 to Oct. 17. For more information, visit dedhamguild.com/makingwaves.
