The web is full of good material on bonsai. Inspite of
that, this list is relatively short, and my intention
is to keep it like that. Only personal favorites
and sites with a focus on bonsai workshops,
case studies, or other type of work that
shows development of an individual
bonsai with a series of pictures.
