Firstly create a new document at 1024px x 970px and start off with selecting the ellipse tool (U) and drawing a large circle (hold SHIFT to constrain the proportions) and make the top of the circle nearly touch the top of the document and the bottom of the circle nearly touch the base of the document.
Change the colour of this new shape by double clicking the colour next to your shape in the Layers Palette and then entering #1f0e6d in the space underneath RGB.
We now need to duplicate the world shape by right clicking on the circle we’ve just created in the Layers Palette and clicking Duplicate. We need to scale this down slightly, so press CTRL+T and you will be switched to Free Transform in which we can manipulate the shape freely. Scale the shape down ever so slightly by selecting the top-right resizing handle and by dragging inwards whilst holding both SHIFT+ALT.
