Children can color stock images of princesses, animals and more, or they can be given a customized coloring book that is chock full of fun family photos of all the people they know and love. A truly personal and thoughtful gift, these customized coloring books can be made by family members or even by friends who are looking for a meaningful gift for a birthday celebration or even Christmas event.

Instructables user PenfoldPlant has created an easy step-by-step guide to create one's own customized coloring book. He uses a free online platform called Pixlr, but also notes that Photoshop and GIMP can also be useful if people have the programs on hand. Once a photo is chosen, all a person needs to do is edited using one of these programs to desaturate, invert and flatten the image.
