Word List Twists _ Choose an interesting theme, make a word list, and then use only half the words in the puzzle. I once made a puzzle about roses for a newspaper. I called it "A Thorny Puzzle." I included a list of 22 words related to roses and then asked the solvers which 11 of these words were actually in the puzzle. Or, write a listless word search. For Grandpa's vegetable puzzle, for example, you could hide the names of ten vegetables and not tell him which ones they are.
Another important thing to remember is making sure that you have enough ink in your printer. This includes color and black depending on what kind of game you decide to print out. Allow the print out enough time to dry before picking it up, some games will use a lot of ink and it may still be damp when it's done printing.
