This is Lesson #3 for the ScrippyMe Yahoo stationery group.
This type of stationery is known as a transition. There are different types of effects one can achieve with a transition. In this particular stationery, the effect is achieved by varying degrees of transparency of a single image. However, the snow layers were not made transparent. Also, a frame was added which would remain visible even though the main image inside would fade in and out.
To achieve this effect, it was necessary to insert a positioned container with 12 top border scrolls.
