Adding Strokes

To add the strokes, create another layer, and select a path. Clicking the “stroke” button in the paths panel (the little circle outline at the bottom) will create a stroke around the path based on either the current brush selected, or the default brush if you don’t have an appropriate one selected. To change the default brush, right click on the the path, and select “Stroke path…”. This means you can create a line based on the airbrush (using the current brush size and foreground colour), paintbrush, blur, smudge, or any similar style tool. For our cartoon, you will probably want to use a fine airbrush, setto black.
	Repeat this with each path in the image. It is often best to create a new layer for each separate element, so you can edit them individually later if you need to. Using thicker lines on paths around the edge of the object, and thinner ones for detail inside it, can create a nice effect.
