Brainy Part starts at: 14:05; Behind the Redwood Curtain starts at 28.20.
Catherine talks about her progress on the Meadowlark Shibori Jacket by Gina Wilde out of Alchemy yarn and her new project Clapo-Ktus by Loredana Gianferri in a beloved skein of Goth Sock.  Margaret kind of winged it with a long, narrow drop stitch scarf out of  Recycled Sari Silk.
Then in the Brainy segment, Catherine talks about how meditation can actually increase the grey matter in your brain and reduce the size and therefore the reactivity of the amygdala.   She also shares information on a program called Knitting Behind Bars.
Margaret describes the logging history of the redwoods and current efforts to be more sustainable.
Catherine's knitting tip is change up needle sizes when you're knitting -- have one project on larger needles and another on smaller.
The incentives to join the Ravelry group continue.
