Following a very thought provoking critique from Sian, I decided to explore a few things in Chapter 8 a bit more.
Firstly Sian suggested making the fabric insert in the seam act as a transition between 2 different fabrics. Below are 2 attempts.
Next, to try and make the join on one particular sample (image 2.8.3 in the main Chapter 8 post) more important but keeping the shapes of the pattern.
And finally to make some strips that are more organic.
