You saw the footprints and read the words. But you probably did not notice that the print patterns are different. Kids would have seen the difference right away.
But that’s not the point. People, especially kids, do not pay attention to ordinary-looking signboards.
Use this footprint sticker idea as a starting point in creating eye magnets. How about hand prints on walls? Paw prints on furniture?
If your products or services are aimed towards kids, you don’t even need to pull their parents in, because the children will do that for you.
All you need to do is catch their attention.
