I am not an expert at this, but have done some. I went to your previous posting and I think the blocks are wonderful. I did notice a stylus that I assume was for making the points sharp. When I tried a pointy thing, they were wonky. So I made a triangle out of cardboard that was the depth of the turned back part. Then I inserted it and lined it up so that the edges were flush with the cardboard and the tip was "squared" with the rest of the block. Pressed it well. Next time I will use a more sturdy template, but cardboard worked for me that time. Then I sewed the blocks together and they all matched up lengthwise and came out evenly where the notches meet. Hope this is clearer than mud. But as I said, I thought the ones on the other post looked pretty spiffy to me and I think you will have a great project.
