As I was ordering yarn from Rosa Pomar, I came across a knit piece in her on-line shop which showed how to use Noro yarn in a more witty way. I had to give it a try right away. You have two Noro skeins and you knit a zig zag pattern and you switch the two skeins in every row. Sometimes the colors melt when they get similar. It doesn't matter. It is a part of it. Also, I have the zig zags in different size, sometimes three knit rows, sometimes four. It is more scattered that way.
The yarn is Portuguese, the gray and the brown one, the colored one is Nimbus, merino, Atelier Zitron in Germany.
