Christine, who lives in Canada, has a regular podcast called "Scrap Time" and I find it incredibly useful. Christine covers techniques, tools, kits, products, ideas and anything and everything stamping and scrapping related. When she compared white pens and showed samples, I realized that there really were some decent ones out there. When she tried one label making tool and it didn't work, she showed what it did and I won't waste money on it. She's both a scrapbooker and a cardmaker. If you have iTunes on your computer, it is well worth the effort and the time to download her podcasts and watch them. She demonstrates as she goes along, and you can see what she is doing, as well as hear her talk about it.
If you go to her website, on the right hand side, there are links to subscribe to her podcst and to download the podcasts that won't show up when you subscribe to her podcast. She will need to update those links soon, because iTunes only keeps the most recent 100, and she's gotten to where her current and her older podcasts have a gap of a few missing podcasts.
