Artist Mandy Greer is creating an artwork this summer at Camp Long--working with the public to crochet, knot and twist recylcled fabric into artwork.

Titled "Mater Matrix Mother and Medium," the project includes the temporary installation of a 200-foot fiber "river" and a dance performance. "Mater Matrix Mother and Medium" celebrates the splendor of Seattle's urban creeks and encourages stewardship of essential watersheds.

Greer's residency begins this week. The public can meet the artist on Tuesdays and Thursdays between June 23 and July 9, from 11 a.m. to 2 p.m. at Polliwog Pond.

"I have been chomping at the bit to begin the process of installing this giant river form into the woods at Camp Long, so am excited to say I have started," said Greer. "It's a slow, laborious process, like putting together a giant puzzle (...) but it's really fun!"

The project culminates with a performance produced by Greer in collaboration with choreographer and dancer Zoe Scofield. The performance will take place July 16 at 6:30 p.m., near Polliwog Pond.

The Water Calling projects are commissioned by the Seattle Office of Arts and Cultural Affairs with Seattle Public Utilities (SPU) 1 percent for Art funds. The projects reflect SPU's management of the complete cycle of hydrology for Seattle's water resources from drinking water through drainage, and Restore Our Waters, the city's initiative to protect and restore Seattle's urban waterways.
