This is a new style big flower hemp hat similar to the natural color one on the same Big Flower page.  The flower on this one is bamboo.  The bamboo is a natural plant fiber that looks like silk but isn't.  It's lovely to work with and very soft. The hemp is light weight, soft and comfortable for warmer weather.  The flower looks a bit too blue in some of these photos.  It's more lilac and less shiny.
