I used two milkweed pods as front and back cover of the book. It is fragile and also rather hard to tie this closure. I think this yarn works well though.
The back page. I have always wanted to make an artists book in which the "theme" and materials come together like this.
This is the first one that has worked. It may be hard to see in the photo but I glued some of the fuzzy milkweed fibers to the pages as well as just the little brown seed in some instances. Charcoal line sketch. 1 1/2" x 3"
