Keep doing this until you have reached the desired size. I won't go into detail in this Instructable regarding how to make a specific garment or item. But I will give you some tips on weaving. Because of the pattern, you have a couple different "fabric" geometries you can work with.
The first is the diamond geometry, each link is connected to 3 others The second is the square, each link (except those on the edges) uses pattern's full 4 to 1 connection
As your swatch gets larger it might be easier to flip it over to continue weaving, because you will need to handle the main body less as you attach new links.
