The Seoul Museum of Craft Art's Night Workshop: Autumn Glass Art runs on only two Fridays, September 18 and October 30, 2026, not daily between those dates. Each 18:00–19:30 session takes place in the education room on Floor 1 of Exhibition Building 3, where participants independently make a collection-inspired glass-art mood lamp. Admission is free, with 30 first-come online reservations per session. The Seoul booking page lists registration opening September 11 at 14:00 and ending October 29 at 23:00, but remaining places are unverified. Adults are recommended; children in grade 5 or above must reserve with one accompanying guardian as a pair. Doors close at 18:00, so arrive by 17:50. Phone 02-6450-7071. This is a reserved workshop, not daily walk-in admission or a take-away-only kit.
