crisscross

We reach the first barrier, which is like the barriers blocking off roadworks, or dug-up sewers: a wooden crisscross painted in yellow and black stripes, a red hexagon which means Stop.

A definite advantage of the fact that no fill-in-the-blank sentences are used is that it's very easy for kids to enter their own words and see them instantly transformed into crisscrosses, word searches, and other fun games.
