Using a crochet book I almost managed to copy a picture pattern of fan stitch. Today I will try again an actually follow each row of the picture pattern. It's in five steps and I think I almost got it, this took three attempts and alot of time.
Here is my free form crochet that I have turned in to a sleeve. 
This is the bust part that I have attached to the sleeve, so I am working from the sleeve across.
