You use the threading in the PDF to weave all the samples in Episode 8. The treadling ideas come from the Point Twill Gamp - Episode 4 followed by the Undulating treadling from the Large Threading Gamp - Episode 5. Jane describes this sample in detail in 4.8.3 - Shadow Weave at the Table at the 6:50 minute mark. Hope this helps.
