Yes Tara whenever we go on a paint-out we post a message on the main page, The events section show the paint-out on the left side of the page under "Main". I'm in Blackrock myself, but I'm not painting regularly at moment as I'm in West Cork,
Norah Blount and Sally Downey regularly post the venues , but anybody who's a member can post any outing , and others will come usually. you will love the challenge of finishing a painting in 2 - 2.5 hrs en Plein air, and it certainly teaches one how to simplify. often you will get people painting mid week around Dublin itself.
Welcome Tara, Hope you enjoy the Site, Join a group or even start your own, I'm a member of The Boyne Valley Group, for example, we meet on Saturdays and paint around North Dublin and up as far as Annagassin Clogherhead etc. All Skills Levels are most welcome. enjoy!
