I heard on one podcast that you should give a podcast at least 3 episodes before you decide if you like it or not. These are the ones that have made it past the 3 episode criteria - in no particular order they are:
The Savvy Girls Podcast features two sisters - Melanie and Deborah. Melanie is living in NYC right now and has an amazing singing voice...she's a bit of a knitter but not as much as her sister. Deborah is living in Bogata and knits quite a bit. They have some wacky adventures when they are together and their banter back and forth with their Canadian accents is wonderful.
Never Not Knitting is hosted by knitwear designer Alana Dakos. She has a very calm voice and she tells of her designing efforts. She often has great contests (not that I've won yet) and sometimes has special promotions where you can buy patterns at a discount (that I've done). She has interviews with other designers and sometimes has "essays" where other designers tell their back story.
The Knitmore Girls is a mother/daughter podcast featuring Gigi (mother) and Jasmin(daughter). These ladies knit a lot and they have great input and advice about patterns, yarns, etc. It was the Knitmore Girls that put me onto The Knit Wits (very funny bit about Gigi describing Rick's voice and comparing it to dark chocolate and Rick's response in one of their podcasts).
I've also listened to Knit Knit Cafe which is a mother/son podcast and is relatively new. It has potential and I'm sticking with it for now. I do check out the Webs podcast - Ready Set Knit. They discuss yarn sales at Webs and I've found some good ones this way - they have good interviews too.
That's it for now...next post I promise I'll show knitting. I almost have 2 FOs to show.
