To draw bark of a tree using Sketchbook, follow the steps given below:
- Create a fresh canvas
- Open the color palette, choose brown and cover the whole page
- Pick the color black and choose the Wheel Pencil brush
- Now begin drawing random lines on the canvas. Make sure to vary their width and length
- Draw some connecting lines to join the two bold lines
- Now make a copy of this layer and give the original layer a Gaussian blur
- On the layer below, apply a blur filter. Next, pick the top layer and set its blending mode to Overlay
- Create a new layer, choose a slightly warmer shade of brown, and then simply fill in the space between the lines with this color
- Select Lighter Color in the blending mode
- Add Moss Effect and now just shade some areas on the canvas. This gives you a realistic looking tree bark.
