Check out "Let's Hang!" in the current issue (May 2020) of Real Simple magazine. Great picture hanging tips and a great article subtitle: "Art can help a space tell your story. Learn how to buy it, where to find it, and how to arrange it for a room that perfectly reflects you and your family."
One place to shop for art: www.nestingcards.com and our fantastic NestMaking artists.
Another: NestMaker Lorelle Rau (image seen here) is selling her NestingCards at Capitol Contemporary Gallery in Boise.
