==Step 1: Design a Puzzle==
[[File:Sliding Puzzle Design.jpg|thumb]]
To create our design, we raster an image into a sheet of MDF. You can create a design from scratch using Inkscape, however, for this example we are using an image found online.
This will bring up the Trace Bitmap menu. Notice that there are several trace modes (Brightness cutoff, edge detection, color quantization, etc). These are all slightly different and some modes may work better for different images. For now let’s select “brightness cutoff” which will turn pixels black that are between a certain brightness range.
