The workshop is open for public since I believe mixture of groups whoever is interested in sustainability is more benefit for everyone to understand each other.

Making a poster for the workshop seems a small thing.  But I learned a lot from it: how important to choose 1)the words/sentences to express what I want to do clearly and simply, 2)picking the photo/frame that suites for the workshop, and 3)whom/where to distribute.  It is very similar with marketing.
