Dublin Sketchers always welcome. There is a dedicated group page for DS here: ( http://pleineire.ning.com/group/dublinsketchers ) and here is our 'How Do' page: ( http://pleineire.ning.com/page/welcome-page ).
I hope you like the site and get some good things out of being a member. Please consider using a photo instead of a drawing as avatar as it helps where people are meeting up in reality (as opposed to internet buddies).
Happy sketching and painting.
