There are many signs of spring around Asheville — the return of the downtown gallery crawls, hula-hoopers and outdoor seating. And this: Curve Studios 2013 Spring Open House Weekend and Twilight Party. The open house is a chance to visit the River Arts District studios belonging to Curve building artists (work includes textiles, button art, ceramics, lamps, oil painting and more) on Saturday, April 13, 10 a.m.-8 p.m. The twilight party starts at 5 p.m. with snacks, drinks and music from Marley Carroll (at 5 and 8 p.m.) and Akira Satake (7 p.m.). Free. http://www.curvestudiosnc.com.
