Thin posts (tiki torches) along walkway with round lights or chinese lantern style stringers between. Up high enough to stop cats/dogs playing with them or people tripping over them, cemented into ground with rocks if you have a problem with things being dug up.
Very detailed instructions for hanging Outdoor String Lights. The arrangement can be changed but the idea is the same. This would be easier than hanging lights from the house to the garage as we did for the wedding.
Creating two levels of hedging by underplanting the raised hedge is a nice twist on the stilted hedge that has become popular with garden designers in recent years. Here we see a formal low-clipped boxwood hedge under the raised hedge of Photinia x fraseri 'Red Robin'. Both are evergreen, creating great year-round interest.
