You will need some chunks of logs that are wide enough and cut straight enough to stand on their own. On one side use an auger to drill a hole wide enough so that the base of a solar light can fit into it. Use e6000 and glue the base of the solar light into the hole. Now stand the log in your garden or on your deck. So much better looking then just pushing these guys into the ground plus you get light up a bit higher which will be more useful.
