Those who read my blog Running with Dogs know about my other passion - running. When running on the road it's important to make yourself visible to others, warn them that you are there.
Here's a design I made in Pages to go on my t-shirt. It is based on the usual widely recognised triangular warning sign on roads.
The runner's figure is drawn with iWork's draw tool (pen). Behind it is a white triangle, a slightly reshaped Triangle from the Shapes menu. And at the back is the red triangle with rounded corners. I made it from the Rounded Rectangle, which is available in the Shapes menu. I made the shape editable (Format > Shape > Make editable), then deleted one of the corners and reshaped the triangle.
