Tang hua seng is a department store with two branches: one across the river in Thonburi and one on Khao San Road. They sell fabric, fat quarters, batting (white or black), thread, rotary cutters and blades, and craft supplies. I noticed ‘sa’ paper, burlap, terrycloth, and velcro in pink, red, green, black and white up to 4″ wide. Tang Hua Seng is on Nancy Chandler’s Map of Bangkok, 25th Edition
