Learn how to branch weave with eco-artist Sharon Kallis. She'll teach participants basic weaving techniques to work together and create large sculptural forms from Â鶹´«Ã½Ó³»Park Board maintenance clippings of alder. The completed sculptures will eventually be installed in the trees outside Science World. The workshops, which are free, will be held Aug. 22 and Aug. 24 from 6 to 8: 30 p.m. at Creekside Community Centre (1 Athletes Way). Visit branchweave.wordpress. com for more information.
