There are some lovely patterns in this book and plenty of new stitches to try out. It is well set out, clear instructions and good photos.
The downside is that as it is an American book not all the yarns recommended seem to be available in this country.
I am knitting the hat at the moment and thought I could use a DK yarn double and that would bring it up to the thickness required. However, this isn't the case. According to the pattern I should have finished the hat quite a few rows ago but it isn't high enough yet so am keeping going.
I will keep trying to track down the yarns on the internet as I really want to make most of the other patterns.
If you are 'into' loom knitting I think you would really like this book.
