What kind of classes? Jennifer McGuire is doing a technique class on her blog with Two Peas website. It is a 9 week program and she does videos every Monday, Wednesday, and Friday. Each week she uses a different medium. So far she has done paint, alcohol inks, and distress inks by Tim Holtz. It is all free and it is great stuff. She is an amazing artist! You can check out her blog for more info or pm me if you have questions about it.
