I like the Missouri Star videos and will always watch those. I like Fabric Cafe videos they are always uplifting and fun. I use to watch Donna Jordan but lost interest along the way. The Last Homely House sometimes is just too much for me, just too much focus being laid back I guess. But I admire her. Dave's Craft room is a hoot. I laugh in a good way watching those. Videos I don't care for are quilting persons with lots of tattoos showing. I keep thinking they need a bath. I watch quilting you tube when I'm in my sewing room so probably have seen all the quilt ones new and old. I have ad free youtube because I watch so many of quilting ones. I like the quilt shop videos that open the new arrival of fabrics. I don't watch the live selling of fabric from the shops that have that. I search for specific techniques or features, troubleshooting on sewing machines and new quilting tools. How to use a special ruler.
I watch too many to list and there are great learning videos from the quilting greats you can find by doing a search.
