I love podcasts. It doesn't matter if they are audio or video podcast. As long as the audio and content are good of course! Last year, I published "My Favorite Podcasts" blog post and I noticed a lot of readers are searching for new content and good podcasts to listen to.

Bhooked crochet. This is on iTunes as audio but she also has an excellent Youtube channel with lots of patterns and tutorials for all Levels. I like Britanny's teaching style so much that I purchase her Craftsy Tunisian crochet class. I am learning a lot and will share in a later post my progress and projects.

As you can see, I like to listen to a variety of topics, not just knitting. I normally listen to podcasts when I am driving, walking the dog or cleaning. I hope you find inspiration and learn something new while knitting or crochet or sewing.
