For my sweet Mom-in-law's (hate that phrase, sounds like you are obligated by law to like each other) Birthday I made her a framed piece of art using my boys' silhouette's.
I just used photoshop to outline them, then filled the background in white and the boys in with black. Easy peasy. In retrospect I would have used a white background for Kai because his hair blended in too much and it was hard to find that contour. Next year I'll know.
