Throw it over your shoulders, and wear it kind of like a scarf for casual times. If you are going somewhere a little bit more fancy, wrap it around you like a sheet, and tie (or leave) it in the front. For visuals, just do an image search for "pashmina". Hope that helps. :)
Do a search on "How to wear a pashmina" and you should find some youtube videos to watch. They show different ways to fold or drape them. A stole size is a bit smaller and is easier to fold. I bought mine from www.kashmirpashmina.com and they have pure pashminas in many colors. I usually don't get fold mine as I like to show of the embroidery but it depends on what kind you buy, the thickness and size. If you fold something too thick it will be uncomfortable around your neck.
Go on You Tube and type in how to wear a Pashmina, you will see many videos on how. Great ideas. Hope this helps
