We have already explored a few of the effects that PowerPoint 2007 allows to be used on shapes, and that’s the reason they are called Shape Effects. Soft Edges are one of these effects, and we’ll look at what you can do with Soft Edges, which adds an eaten-up, feathered edge to a selected shape. Soft Edges work best with larger shapes, especially if you use some of the larger Soft Edge variations available. PowerPoint provides some ready-to-use Soft Edges, but there is no option to format Soft Edges beyond these readymade offerings.
