It is made from silk neckties, and men's wool suits (all thrifted fabrics).
I really like that she was not afraid to mix both fabric content and texture.
The finished blocks are less than seven inches, with individual logs cut at 1-1/4" to render 5/8".
Whew, that is really small when you're dealing with slippery silk and nubby wool.
