Batik : Wax resist painting with indigo (video)

When I first saw this video, the amount of leaf needed to make the indigo dye, as well as the time it took to make it, was what struck me most. The wax resist (done in two dips to make two shades of indigo) was beautiful, but for me the amount of time and space it takes to make enough indigo to do the piece is what really struck me.
