In this week's tutorial, I go over a simple trick I use a lot when designing trade show banners, and other graphics at weird widths. By using transform, you can actually stretch and pull your images ever so slightly to avoid having to clone or otherwise generate more image data when you need a wider image than you have. Seems simple, but a lot of people don't think to try it.

I also find that Content Aware scale works well in similar instances. You get the same transform benefits, however it helps reduce some of the obvious "stretched" looking elements that often appear when using a straight-up transform.
