Sometimes, your place of employment may not have the funds for fun software like Snagit by TechSmith.  This was the case with me recently, so I have really been honing my skills on PowerPoint and using a lot of the embedded image editing tools to make our training look more professional.

Today, I was making a slide that reviews some learning materials that was covered previously, in order to bring that into my learners working memory.  I only had enough space on my slide to keep a portion of an image that I created in a previous module, and was wishing for a torn edge tool.  Not having Snagit or Adobe Photoshop, I went on a short quest to see if I could do it inside of Paint.net or PowerPoint.  Low and behold, I figured out how to accomplish just that using this great video tutorial  by slhice on Screenr.  Thank you so much for this tip worth sharing!
