I’m kind of off podcasts recently (replaced with audiobooks) but the ones I listened to were: Seamwork Radio Sewing Out Loud
There are others, but I didn’t like them as much.
Caveats: Seamwork is definitely trying to sell you their membership model, which I am definitely not interested in. But I found the things they talked about to be at least somewhat interesting.
Caveat #2: Sewing Out Loud doesn’t update anymore, sadly. I also tried starting with the most recent episode; that’s a mistake. The best way to consume this one is to start at the beginning. The ladies who ran it are extremely knowledgeable but they are more and more rambley and tangent-y as they go along. However, I learned a lot from the podcast as a beginning sewist. If you can handle the format and the personalities of the hosts, there’s a lot of gold in it. But it may not be for everyone.
