One of my favorite weave structures is Shadow Weave. In traditional shadow weave every other thread is a dark color followed by a light colored thread. This is done In both the warp and weft directions. The light color is the shadow. My go to book for shadow weave is 1000 (+) Patterns in 4, 6, and 8 Harness Shadow Weaves by Marian Powell. With the many variations shown in this book it is easy to put together your own combinations.
