I saw something like this in the supermarket a few weeks ago and thought “I’m sure I can do that prettier and cheaper”, so one jar and one set of fairy lights later here it is!
I realised the only way to get the power supply into a small jar was upright, leaving the batteries visible through the case. So I wrapped the battery case in foil. The silver reflects and is hardly visible with the lights on.
I stuffed the lights in either side of the batteries. It’s not as easy as a lamp having to take the lid on and off but it looks good 🙂
