Days are short in winter in the Northern Europe, and I notice I miss sunlight. I compensate the lack of enough daylight with some extra glitter in the house.
I found some vintage lamp crystals at a flea market. I had jump rings, pieces of different chrome coloured chains in stock as well as a branch from a hornbeam in my garden.
The crystals give an illusion of more light than there really is in a cloudy day and in afternoon sunset.
The rare occasions of direct sunlight make the crystals sparkle and cast rainbows on walls. It does not matter that the crystals are different in shapes and sizes, and that there are some scratches. I wash them a couple of times a year in warm water and a drop of mild soap.
