Tailored Collar!

 

I learned how to make an origami tailored collar

when I attend the origami course hosted by Shingo Sato.  

 At first I had to make the pattern.  

The drawn lines are inserted with pleats.

Then you have to make it in fabric.
It's best to use cotton, then it's easy to see how the pleats are going to bee.  

The challenge afterwords was to make the collar integrated instead.

This is how it was supposed to be, but it was a bit tricky.
