If all else fails, I suggest you take colored paper and follow what you think the directions say, taping the pieces together to see if the block will come out as the picture shows. When it says to sew a seam, you can either turn the 1/4 under on each side or cut it off. The tape will hold it together. If you don't have colored paper, then use white and just write the color name on it.
Good luck with that beautiful quilt.
