I am assuming that you re-thread to weave the sample #3 of episode 8 to include the undulating, point twill and extended point patterns, correct?
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.
Thank you. I didn't do the large threading gamp which is probably why I didn't understand.
However, I really do like the results of shadow weave, especially when using complementary dark colors instead of black
