RACHEL MARTIN, HOST:
Good morning. I'm Rachel Martin. Sharalee Armitage Howard of Coeur d’Alene, Idaho, had been watching the 110-year-old cottonwood tree in her front yard deteriorate for years. The dying branches were a safety risk. And she knew it had to come down, but she wanted to give it another life. So she hollowed out the stump. She put on a roof and a glass French door and turned that stump into a Little Free Library. It's been a huge hit. Photos have gone viral. One man in Arkansas wrote, don't be surprised when the elves move in. Transcript provided by NPR, Copyright NPR.
