I discovered a free online tool tonight for making crossword puzzles... so of course I had to try it. You can see how I used the puzzle in a post on my community and real estate blog at Focus On Crofton, but let me share with you just how easy this is:
1. Visit Crossword Puzzle Maker
2. Enter the name of your puzzle and your name
3. List words and their clues
Crossword Puzzle Maker does the rest. And they even save your puzzles for you up to two months. Of course, you can make a screen shot of them, as I did, to save in another file or to insert into a blog post.
While my puzzle is a quiz on local knowledge, Michael and Stacy Spickes created an ActiveRain post in 2007 with a Short Sales theme. I think a crossword puzzle is a great break in the routine of a narrative post, but it could be just as informative. Think of the many possibile topics... I am!
EDIT: Great suggestion in the comments from Maureen McCabe. Instead of using an image for the clues, she suggests typing in the text so they're searchable phrases. WONDERFUL idea!
