Test piece arrived today as the first go at getting the colours + patterns right. 1 pattern, 4 different colour choices

The piece of original cloth I've chucked over the top for comparison is pretty faded (the supplier is using a much much better piece as the start point), but it forms a useful basis for comparison.
With this being the first test run I'm really pleased with the results. I think we have a colour match in there, certainly can downselect to 2 choices
2 improvements to the pattern for the next test run -
- Getting the alternating stripes width within the rectangle pattern right. At the moment this has the effect of making the pattern not look dark or light enough, but it's the pattern not the colours if you see what I mean
- Getting the rectangle size right
Another 2 weeks or so for the next test run
