I traveled across 3 states three times this summer with my children. My company: my iPod! I discovered several podcasts and a couple (actually 3 to stay with the theme) of them I really have to mention because I LOVE them.
Creative Mom Podcast: Amy does a great job covering all types of art, creativity, parenthood, etc. I look forward to this every week and I love all of the creative promts and book suggestions. I have also participated in a Artist Trading Card exchange hosted by this group. I have to say I have also listened to almost all of the archive episodes.
CraftSanity: Another great podcast. Jennifer Ackerman-Haywood does an interview show. She interviews current creative minds...many of them fellow bloggers. It seams like every time I discover a new creative person that I enjoy they appear on her show.
Writers on Writing: Barbara DeMarco-Barrett interviews writers, editors, publicists and agents. LOVE IT! Again, I have listened to a lot of the archive episodes, but there are sooooooo many....I think over 300. Anyway, I have plenty to keep me busy and I have learned so much about the writing industry. We will see if it helps :)! I have also discovered some of the best books that I would not necessarily pick off the shelf without hearing the author discuss it on this show. I can also recommend, if you are interested in writing, Barbara's book, Pen on Fire.
These are just a few of the ones I listend to...all great and all pretty popular! Let me know if there is a Podcast you can't miss.
