This is one of my all time favorite DIY projects for the garden. String lights are so popular right now, especially for those who are trying to make their outdoor spaces more beautiful. But oh my have I seen some BAD ideas for how to do this. So many people fill small buckets with concrete only to see the poles and lights fall over in the slightest wind. Or others fill giant buckets with sand, which hold the poles up better, but are kind of ugly and very hard to move. This is an elegant and easy way to get the job done!
