Watch this video first to learn about navigating Shell Sketch, then scroll farther down the page to get to the drawing program. You’ll need to zoom or magnify the screen to make it larger on your screen. Do this by clicking on the three dots below the X to close browser. Find zoom in the menu and make it 175 or 200% to fill the screen. Also click the full screen box to the right of zoom control. The program is below the video and takes a moment or two to appear.
