Busking/street art in Greece?

[Irina]

Hi, yall, I am contemplating going to Greece for a month September-early October - mostly to see the country and ancient sites, but I'd love to do some face-painting on weekends or at festivals...I understand that they have bad financial situation right now, so I intend to do it mostly for fun/pictures/pocket money - but I wonder what are the rules, do people speak English, how safe is it etc etc. Would appreciate any suggestions! Thanks, Irina
