This is a Showa retro heda-dai (ironing board for sewing). It is a board that easily shows the marks of the heda (ironing tool) when sewing Japanese clothing. It has instructions on how to cut kimonos and haoris, which I used as a reference while working. Size: 38.3 cm (length) x 26.8 cm (width) x 4 cm (thickness) It has been stored at home for a long time, so there is discoloration due to age and discoloration on the metal fittings at the corners. Please consider this before purchasing.
