shuggastiletto, i'm not sure how far northeast you want to get, but nscad university in halifax, nova scotia (just north of maine) has some really good summer continuing education classes. are you looking for just fashion? there is a garment alteration and redesign class that i'm taking, as well as intro to weaving, textiles manipulation, dyeing...and if you're in highschool still, there are teen courses that also look really awesome: fashion redesign, self portrait in wire, graphic design and animation...here is the website:
