Glad to be of help everyone!! :D :D :D
I finished the rest of the 30 9 patches yesterday, and discovered that it is best to use a slightly shorter length stitch, then there is even less room for movement between the intersections. t The closer you butt the pieces together, the better. You still have to ensure then are nestling correctly and I prefer to 'feel' a tiny ridge where the two vertical edges are really rubbing together, then if they move slightly apart while being sewn, they are still well in line :D
Does that ramble make any sense ?? :lol:
