After conventional machine washing use a fast spin, then hot iron while the hemp is still damp. This makes for ease of ironing and will maintain appearance. Use a hot iron. Hemp easily handles extreme temperatures.
Stretch the damp article to its natural size and shape before ironing. A hot iron will ensure that creases and crumples disappear instantly. Every piece will come up so crisp and new that it is impossible to tell whether starch has been used. Iron the 'wrong' (underside) first. For colored dress hemps, only iron the wrong side. This preserves the texture of the weave.
