Here's a hint - they're round with a cheery soft glow:
You're guessing lights? Correct! Seven or eight years ago we decided to put lights around the perimeter of the ceiling of our upstairs porch. We bought some really cute dragonfly lights from Smith & Hawken (don't you miss them?) and used them for several years.
When they too rusty and tatty to use, we purchased some outdoor lights with small, round globes - these were festive, but fragile - and after losing several globes each year to breakage we decided to toss those at the end of last season.
So this year we were unsure what to do and I happened to see these strings of paper lanterns at Target. They're larger than the lights we've used previously and this led us to hang them lower with the shades visible from the street. We're very pleased with the effect and hope they last for several seasons.
If you need some great lighting on your patio, porch, garden, or deck - check out the selection at Target. They're sure to have a style that suits you - flower pots, old-fashioned globes, paper shades (like ours or in bright party colors), lanterns . . . and hurry, so you can enjoy them all summer!
