But we want the lines to curve, so we are going to do something called editing its nodes. You will notice that it is made entirely of straight lines.

Finally, connect the last line to the beginning to make the object. make the face so that it goes about halfway over the hair (see images). When you reach the hair, DO NOT just trace the hairline. When you get to the ear (if it is visible) just pretend that it isn't there, and imagine what the face will look like underneath the ear and continue. Keep doing this all around the outline of the face. We want to keep as much to the outline as possible. If you have a steep curve, make it closer. So move your mouse to another point near the starting point, about an inch away. The bezier tool will draw a straight line connecting the current location of your mouse and the place which you just clicked. At the end, we will join it up to make an object. It makes this spot the beginning of the path. We are going to trace around the outline of the face, then fill it with a gradient fill in the color of their flesh. To use this tool, pick any spot around the outline of the face in your photo. This tool is really handy, and we will be using it A LOT in this instructable. Select the Bezier Curve tool from the left side toolbar (see image below).

To do this, we will use the Bezier Curve tool. Now we are going to make a path around the outline of the face. It is important to make sure that it is in the right layer, as when we remove the photo, anything linked to it will also be moved, which we DO NOT WANT. The layer that you are currently working on will be hi-lighted) then we will not create anything joined to the photo. As long as we stick to this layer (frequently check the layer editor to make sure that you are on this layer. You now have a layer called face which is automatically placed above the photo. We just need to worry about the name, so as the name type in 'Face'. A small window should pop up in the middle of the screen, asking what you want to name the layer and where the layer should be placed. To create our new layer, click on the green + icon in the layer editor. The layer editor will come up on the right hand side of the screen. The icon that shows the sheets of paper stacked on top of each other is the Layer icon, click on it. At the top, there is a horizontal toolbar. To create that layer, we first need to open the Layer editor. This layer doesn't include any features, it is just the base of the face. Now that you have your photo open, we need to make a layer for the face.
