Work with an outline or fill overview
You can work with just an outline overview or have the object filled the same way as you would typically work with any vector object in Adobe Illustrator.
Edit stroke parameters on the control panel
Ellipsis properties can also be changed from the LTTR/INK Controls Panel.
Edit stroke parameters on canvas
When the LTTR/INK Tool is active, individual Nibs are visible. Their handles can be dragged on the artboard.
Edit the skeleton
You can always change the shape of your design by adjusting the skeleton.
Pro tip: Draw just a rough skeleton of your design then switch the LTTR/INK outlines as soon as possible. It’s easier to draw with visible outlines.
