Seoul Public Service Reservation lists the 2026 flower-ball making program at Yulhyeon Park's reading shelter for November 11. It is restricted to adults, with eight first-come places. Booking is scheduled from November 2 at 09:00 to November 6 at 12:00, so it was not yet open at the time of verification. The page calls the session paid but says the precise price will be announced in stages. Do not rely on an assumed fee; recheck session times, materials and pricing in the updated notice. Enquiries: 02-459-9923.
