The Korean people learned to use various fabrics, such as sambe (hemp), >mosi (ramie), cotton and silk to make a range of clothing that was not only attractive but also provided them with effective protection even during the harshest winters and the hottest summers. They made warm winter clothes using the technique of filling soft cotton between two layers of material, silk or cotton fabric, and sewing them together with fine stitching, and produced cool summer clothes with hemp and ramie. These clothes typically feature graceful lines and forms that create the serene aura characteristic of the traditional Korean clothes we know as hanbok.
