I purchased this at a Yoko Arimoto exhibition over 20 years ago. It's a wool felt pot mat / trivet. Simply placing it down softly receives the resonance of different materials like wood, ceramics, and metal, creating a sense of tranquility in the space. The beautiful "pure white" of the undyed felt has maintained its clear and transparent appearance over time, without any clouding. The small hole is for hanging it to dry, and it also serves as an accent, subtly adding to its elegant functionality as a tool. When you place a teapot, kyusu (Japanese teapot), or small pot on it, it gently cradles the weight of the metal. It also elegantly enhances seasonal fruits or small objects when placed beneath them, acting like a display stand. "Using" and "admiring." It's a quiet everyday tool that caters to both. My heart is cleansed by the pure feeling of the white felt. You can create a small world with just one piece of felt. As a display mat for your interior. It becomes a sophisticated item. Felt tends to absorb moisture, so it seems there's a culture of hanging it to dry. I understand the reason for the hole. I think it's a "rare everyday tool" that you wouldn't find nowadays.
