Just like hairsticks... any style you can create with both hairsticks on the same side, you can pretty much do with a 2-prong hair pin.  You can also use one for "show" just like hairsticks, too.  There's a pic of my hair in the Customer Gallery with my Harvest Queen hair pin tucked into a really kewl style I did with a Hairagami.  You can see it at the link below:

I'm currently debating on retiring the line and focusing more on vintage pieces... it's difficult to do everything I want to do!
