The word "Paisley" is missing from the instructions. The instructions should read as follows:

4. Unit III

Using the same construction techniques that you used to construct a Unit II, make a Unit III using 48 Red & Pink A squares, 48 Dark Red A squares, and 24 Cream & Red C squares for the squares-in-a-square.

Use 48 Navy Paisley As and 24 Cream & Red Ds for the flying geese.
