If you have kids, you have balls—basketballs, soccer balls, rubber balls, and other round objects that roll around underfoot. Here’s a perfect way to use that narrow gap between a pair of garage doors (if you’re blessed with such an awkward spot). Just install angled “ball ramps” made from scrap wood. The balls fit neatly in the gap, and because the ball ramp is right there at the edge of the garage, kids are more likely to use it.
