A Furoshiki is basically a 45″ square of cloth which can be tied and wrapped in a billion different ways to do different nifty things.
The Furoshiki I made for Calluna was just a big square piece of fabric hemmed around the edges (though, wow, I had no idea how hard it could be to sew four long straight lines correctly).
No picture unfortunately, but it was a grey green with stripes.
Here’s a link to a page with more info and great pictures:
