There is a reason this is classified as "advanced" on Jinny's website.
You should probably piece the four outside sections (6, 8, 8, 5, 4) first, then the four star sections should be next (2, 3, 3) and (2, 7). Finally, the center (1, 1) and join all the sections together.
Since Jinny does not add seam allowances to the pattern pieces, it should be fairly easy to print out several copies of the templates, trim them down and tape them together for a paper piecing project.
