I love Erica Arndt on Youtube. She always has some interesting project going on. Also love Donna Jordan, MSQC, a lady in England (can't think of her name) but she's so sweet and fun.
I don't know what I'd do w/o Youtube. There is a tutorial for everything possible! My husband and I both find answers to questions from computers to plumbing etc.
I follow a few folks not related to quilting as well. Gardening, nail polish, stuff like that.
