From Parlez-Moi Press / Valentine-Design.
Kathleen has released the pdf download version of her pattern book. In my opinion, from just a quick glance through it, it is well worth the money.
Only about 50 pages, but multiple designs, commentary on HOW to design, selecting yarns, etc.
It's something I am going to want to study in depth.
