In the ongoing (& on-growing) effort to educate re: being an educational illustrator, here are some more semi-recent mazes that I've done.

Above is a fairly straight forward maze. Not a lot of paths that you'll stay on for hours before you discover they're dead ends. The simplicity of any maze that you'll design will have a lot to do with the intended age group. Because this particular puzzle was for YE (younger elementary), it needed to be fairly simple. To counteract the simplicity, I used color variation in the paths to throw the kids a bit of a curve ball visually.

I know what you're thinking.

The above maze is really easier than it may look at first glance. I wanted to make things look more confusing by using squiggly lines, and by making use of the red arrows as a border. Not only does it make the puzzle look tougher, but it makes it more interesting for me to do. I don't want to be bored while working on an illustration, because if I am? Chances are good that the kids will be too.
As an educational illustrator, a huge part of your job will be to inspire kids to do work that will grow their brains. It has always been my contention that if you can make WORK look like PLAY, that if you can make kids WANT to sit down to work on problems, well then: you've done your job well.
Getting revisions on these types of squiggly mazes after faxing in sketches is always fun.
Here's an example of how these conversations usually go.
Art Director: See that line about 3 squiggles over from the 1,2,3,4... 4th red arrow on the top of the page?
Me, looking and counting: Um, yeah?
Art Director: OK, that path needs to be closed off.
Me: Got it.
I'm not sure why we never do this correction stage of things via fax as well. Maybe it's because we like to hone our ability to communicate effectively in the verbal format.

The above maze uses "tunnel and bridge" paths, and to that end: words & their meanings are linked.
To keep the children confused (always my aim, despite what my nicer personality may tell you), I keep the paths in these types of mazes the same color. If you made each path a different color, it would take away the need to trace the route to see where it leads.

The above is another type of word maze, this time using groups of letters that need to be placed in the proper order. Are the large areas of plain green grazing pastures? No. That's where the type on the page goes. That's just one more thing you'll need to take into account when designing your maze: intrusive text.
