For one of our art lessons, we went outside, to examine up close, trees and their bark. We felt the tree trunk's texture, and noticed that they are very rough (not smooth), and that they have many different colours mixed together. Tree trunks are not completely brown........actually most are not even brown! We saw yellow, green, brown, black, white, gray all mixed together in one tree! We used pastels to create the tree's textures and colours.
