I got this idea from another blog (artolazzi - an awesome one if you haven't checked it out), here's the link to the original lesson http://artolazzi.blogspot.com/2009/11/klimt-winter-trees.html
These trees turned out awesome! It took us 3 sessions to make, but didn't take the whole time of each session (we were working on finishing our last project). The kids really loved making these and it was a great way to introdce Klimt! Day 1 we painted the background, day 2 we painted swirly trees and learned about Klimt, and Day 3 we did the decorating (snow, metallic paint designs, sequins and rhinestones). A great wintery lesson!
