Choose the pavers. Choose neutral colored Necco candy for a slate look, speckled halved jelly beans for a pebbled sidewalk or brown sugar for a dirt sidewalk.
Color the royal icing the same color as the pavers. This will disguise the bright white royal icing used to glue the pavers into place. Add a light brown food coloring to look like mortar for a brick path. Or add a brown sugar color to blend in with the "dirt."
Apply a small amount of royal icing directly to the work space. Place the pavers into place. Continue Steps 3 and 4 until your sidewalk design is complete.
Wrap the workspace in aluminum foil, place the gingerbread house on top of that and then the sidewalk. Design the sidewalk on the foil using a toothpick. Then follow the design pattern with the above steps.
