How do I customise a design?
To change a size, use your mouse to drag the red measurement triangle; or click the number box and enter a measurement with the keyboard. Use the buttons on the right-hand side to choose different styles and measurement options. You can zoom in and out using the mouse wheel (or the zoom buttons), and drag the image around with the left mouse button. If you do find yourself getting lost, simply press the Redraw button on the left hand panel. Move your mouse over the boxes for extra information on how things work.
