I have just found this great website that sells scarves, all sorts of styles, colours and fabrics.
(They are having problems with links getting through to their website, so have been asked to turn the link off. Copy their web address and paste into your address bar. Sept 12)
One of the great things about this website, is they have a section devoted to showing you how to tie a scarf. You can choose the type of scarf you have, or are considering buying, then learn different ways to use it. Brilliant.
They also have a facebook page.
