I thought our winter lanterns needed a snowy background, so wheny son was sick we “painted” with toothpaste and cotton:
The photos of the window don’t turn out well but maybe the idea can be seen anyway? The toothpaste comes off easily just with a wet cloth.
Today, two days after we “painted” the snow sceneries on the windows, we even got real snow to light up the darkness. Yayyyy for making our first snow angels and having our first snow fights of this winter about to begin!
