I have put the sashing around the first three colours in the corners.
This is the sequence in which I created them in the first place and it make logical sense to me to do the sashing in the same way.
I redid B1 as it had worked out too small and I redid the round bit on E5 as it way way too square. This has slowed my progress a bit as has the weather.
I am now doing the purples and it is always lovely to see the blocks once I remove the paper.
Have a good one
