Something cool

I bought this old craft book at a sale for used books several months ago.It cost me only a couple of dollars.I bought it just for the idea of the afghan in these pictures.It is crazy cool ,isn't it ?
The colors,the pattern, the arrangement of the squares.There are some more interesting ideas in the book too which I can share in another post.
I started a project inspired by this afghan.I am going to use my leftover yarn on it. But I am going to post about it the next time.
