How to make coloring pages from photos, print them and pick supplies

Before Colorkin was a business it was a dad at a laptop trying to turn a phone photo into something a toddler could color. Most of what I learned along the way works without buying anything.

These guides walk through free ways to turn photos into line art, how to print coloring pages so they do not come out gray and muddy, which paper holds up to markers, and which crayons and markers suit which age.
