Clover Market in Ardmore, PA last June, I signed on to do 3 more shows with them this fall ("them" being Janet Long and her wonderful group of volunteers). Read about how the market got its start here.The shows are one Sunday per month starting on September 18th. Next is October 16th, then November 6th. Even if I weren't going to be a vendor, I'd hop on over there to shop anyway. It's a great group of vintage & antiques dealers mixed with handmade sellers set up in a parking lot along the up-and-coming main street. It's not actually called Main Street, though, it's East Lancaster Ave (12 E. Lancaster Ave, Ardmore, PA, 19003 if you want to program that into the GPS).
Brandywine Festival of the Arts. I attended last year and thought it much improved over previous years now that local arts mogul Barry Schlecker has taken it over. It will be a fun activity to do with the relatives who will be staying with us that weekend for a family wedding.
Come out in the nice weather and support your local arts!
