I had never seen Hundertwasser's homage to Van Gogh until several months ago. Or, most likely, I've seen it, but I saw it as an opportunity to teach my kids about two artist. It was also a great way to talk about how different artist can interpret something they see in two totally different ways.
This art piece took most kids 4 art classes (50 minutes). One day to paint the papers and background paper. One day to draw and cut out the vase/mug, stem and leaves, one day to glue stem, leaves and cut our petals and glue them as well.
And one day to trace, cut and glue the circles. A few kids needed a little more time, but the majority was done in 4 days.
