While I was preparing for this announcement, I realized that 14 of the blocks are not symetrical. You will need to flip the pattern over to the back for the correct alignment if you are planning on using fusible for machine applique.
The blocks that need to be flipped are 1, 4, 6, 7, 12, 13, 15, 17, 19, 20, 27, 30, 32, and 33. Hope this will help.
