Some of the best artwork I've ever seen in my life was from the hands of a child. Unfortunately it is usually done on regular paper that won't last very long or lined notebook paper that just doesn't have that museum quality feel.
This simple instructable shows you how to take a photo of a kid's drawing (or any drawing) in black ink to convert into a vector which you can then print onto higher quality material (or in this case, laser cut for free at Outfab.com
This drawing was specifically turned into a necklace as a present for the child's mother's birthday (best present everrrr, even the kid was blown away!)
I've designed the instructable to walk you through the most efficient manner to make the best laser etch possible. You can tweak the process to make a scalable vector of a color drawing or to vectorize your own artwork for laser cutting. Most people do not realize the importance of contouring to make something stronger, adding a loop, or using pure black & white graphics for etching (as opposed to grayscale).
I use CorelDraw but you can use similar technique with a variety of programs including Inkscape which is free at www.InkScape.org (a great starter for those unfamiliar with vector graphics)
