Have a DIY event, class, or program you’d like added? Complete the online form and we’ll add your info to the calendar! Please submit events at least 2 weeks in advance.  (Please note: This is an informal courtesy service of GCM , intended to help makers share word of activities and programs, and not as the principal announcement forum for your event, or as a free advertising service for your company or product. We reserve the right to reject submissions we feel are outside the scope or intent of our community.)
