10 bestest by Brian Hart, Karen McFarlane Holman

Last Updated: June 13, 2026

Each week Karen McFarlane Holman & Brian Hart spend their time curating the world’s coolest things and then pass them along to you.10 Bestest is a condensed way for you to learn new things to enhance various aspects of your life. We (Brian Hart & Karen McFarlane Holman) take turns spending two minutes describing something – a “cool sheet” – that we use or enjoy. When two minutes are up, Boom! The other host shifts onto the next topic, giving a total of ten cool sheets for each show. Our #coolsheets vary widely: a gadget, a book, a nonprofit, a movie, an app, a life philosophy… anything goes! You can then find out more about each cool sheet by clicking the links that we provide here on 10bestest.com along with each episode.
