This design is very cool.
It is an innovative use of graduated crochet stitch series and picots.

Very stretchy in both directions, which is unusual for crochet.
It worked up rather quickly.

Very good directions.

This is the last of this special yarn that I will ever have.
Projects for my stash of it has been chosen quite carefully.

Pattern called for 280 - 390 y.
This yarn has a greater yardage so I used a bigger hook.
I had just enough.
I really enjoyed making it.
