to make a tree trunk

To make a tree trunk is necessary a brown paper of painter, an elongated cushion or pillow, adhesive tape and a black marker or black labeller.
We cut the brown paper of painter to size the pillow or cushion to wrap it later and we paint imitating the crust of the tree  with black labeller.
We cut two pieces of paper in a circle with the same  diameter  of the pillow or cushion, and draw concentric circles, mimicking the tree rings.

We surround with Large paper the pillow or cushion and we paste it with adhesive tape. The circles of paper are pasted on the sides of the pillow.
