Pictures from Pinterest.
To the left – Spray painted hula hoops (rockringar) wrapped with string lights. I didn’t see from the beginning that this was a xmas decoration, but I think that would look great on a patio/garden summer time.
And to the right -as you can see, just logs and a string light. Cosy, and great for safety if you have small children and don’t want to have a real fire. Same idea would work for a chimney (braskamin)!
