When laying out your design, you'll notice different colored lines on the layout template. Since we're dealing with a 2D representation of a 3D product, we need some extra room to wrap your image around the item - so it's critical that your artwork extends all the way to the black line, or you'll end up with white edges on your item. The solid pink line shows the approximate face of the surface - anything outside the pink line will likely be wrapped around the edges of your item.
