PicMonkey has your standard crop, rotate, sharpen tools, but you'll love the tabs that follow: photo effects, touch ups, text tools, shapes, scrapbooky items, frames, etc. Below is one experiment of mine. I will spare you the rest. (Weren't my twins cute when they were little??)
Try it out and post below with your thoughts. Share a before and after pic if you like! Want a printable guide to walk you through a few of the options? No problem. My colleague, Randi, has you covered.
