I'm a big fan of the art, especially the Native American pine needle basketry, although I've never tried it myself. I have small, but nice collection.
I found the subtitle of the book interesting (From Forest Floor To Finished Product) because the basket makers I know (and certainly historically basket makers) have always worked with green, that is, fresh pine needles. There certainly would be many difficulties in using fallen pine needles, like pliability and the fact that they are no longer straight but twisted and curled. Also lining them up ad keeping them in groups apparently explains the necessary of the tubing, something not necessary with green pine needles which are naturally grouped.
