Nails are a popular choice for hanging string lights, but they are not the only option. Use outdoor hooks, zip ties, or even awning hangers to string up lights outdoors. For indoor lights, use simple tacks, zip ties, damage-free adhesive hooks, or drawing pins. When all else fails, just wrap the lights around some furniture or outdoor fixtures. 

No, you should not leave LED Christmas lights up all year. While the LED lights themselves are very durable, their wiring and casings can be as vulnerable as any Christmas lights. They’re subject to drying out, experiencing cold or sun damage that causes them to crack, and even damage caused by gnawing pests. (The same is true of incandescents.) If you want your lights to last the years that they’re rated for, bring them inside after Christmas is over. 

Between seasons, inspect cords for damage, replace burnt-out bulbs, and clean lighting fixtures to prevent dirt buildup. Proper storage in cool, dry conditions will extend the lights' lifespan and minimize repairs or replacements when redeployed.

If you are hosting a large party this year or have staged your home for potential buyers, having a professionally-decorated tree can make a big impact. Christmas tree decorating services can also be more than worth it if you're unable to reach the top of your tree and need assistance with precarious ladder work.
