I have now completed 2 pages of pattern completely, and a bit more besides. It is not easy going. There are lots and lots of colour changes in just one small area, and rather than feeling challenged by this, I am actually starting to feel bored. There are some large areas of just one colour in 3 out of 4 of the remaining sheets so hopefully I will progress a bit faster.
Over a third completed now.
The first 2 pattern sheets. I highlight an area as I complete it.
