CF1 Ammened design

After looking at the design in greater depth - I realised there were a couple of flaws in it.  The broken twill design had a treadling pattern that hit a duplicate tie up - meaning you would 'unweave' the shot that had just been woven at that stage.

So keeping with the block nature as much as possible I've gone through several redesigns - this is version E - and have the following that I think will still work OK.
