This is her creation! Using fabric scraps, she sews a pouch and fills them with cherry pits! I’d never heard of this before until I saw one that she’d made. She said she’d been using them for years and they’ve been a comfort to her family. You place it in the microwave and heat it for a short time and all of the cherry pits soak in the heat and keep the pouch warm. When the heat runs out, you simply reheat. You can reuse the same pouch for years.
