1. Cross contour Skulls
Mrs Ras

2. First find a skull

3. Open a new file in illustrator

4. File>place your skull jpeg

5. Scale the image and then lock the layer add new layer

6. Choose the pen tool and take the fill off and choose a color ( I am going to work with grayscale so that I can change the shade to add depth at times draw a small cross contour line segment following the curves of the surface

7. Add a completely separate line again following the curvature a little distance a way from first

8. Using the the blend tool click once the first segment and then on the second

9. Double click on the blend tool and change the box options to specific steps and a chosen number

10. Add a new layer for your next segment of lines

11. Consider the width of the line for each surface, should some be smaller if farther away?

12. Using the direct selection tool you can still adjust the line’s anchor points so that it fits you skull

13. Continue to add layers and creating segments of blend tool contour lines

14. Consider changing the direction of the lines to be perpendicular and the weight and size of the stroke to enhance the information about the curvature of the surface
