Things You'll Need
Instructions
Draw lines at three-fourth inch intervals horizontally across a page of white post-card stock. If your model city council stipulated that sidewalk panels must be 5 feet square, you are just slightly larger than code because in HO-scale this would be 0.69 inches.
Draw a second set of lines at three-fourths inch intervals vertically down the same page of white post-card stock. The result will look like a grid in which the individual cells each have an area that is three-fourths square inches.
Cut out the squares. Lay them out so that they do not touch on a piece of old newspaper. Spray the squares with Stone Touch spray paint. This will coat them with what looks like cement.
Wait for the paint to dry before gluing each square in place on the base of your lay-out. You can make long sidewalks by laying out one square next to another. You can also make cement patios and driveways by laying the panels to fill those designated areas.
Make curbs by laying round toothpicks along the outside edge of the sidewalks. Spray them with Stone Touch spray paint first. Glue them down after the paint dries.
