If you're not in the UK, you can find all four episodes on YouTube and they are delightful. My favorites are Ann (81-year-old yoga nut who's been sewing for 75 years), Lauren (sweet spirit with a thick Scottish accent), and Tilly (incredibly creative), who even has a sewing blog. I've been watching/listening to the show while sewing, of course, and have been so inspired.
If you love British accents, competition, and creativity, warm up a cup of tea and settle in... you'll enjoy it so much! (Thanks, Kirra, for the recommendation!)
