Thanks, Janey. I made up some dummy squares on paper and have figured out one way of pressing and laying them out that will work without having the conflicting seams.

You have to press the top and bottom rows in the same direction with the middle row in the opposite direction. Then, press the cross seams in the same direction. Once you slice the 9 patch, you can then flip the diagonal squares around. Then you have no matching seams at all, so you don't have to worry about it.

There may be other ways of doing it, too. I tried to figure out how you can lay it out so that it looks like it is sashed with cornerstones, but haven't gotten that one figured yet.

p.s. Janey, I just looked at the pdf. you found. That layout is the one that will work with the pressing I describe above. No cutting seams or matching seams. (at least it does with paper blocks)
