I discovered this photo of Ilona Habben the other day at Schoener-whonen.
Besides that this image shows a perfect composition and colour scheme (Yes, I had to make a colour palette around this picture) – it also provides a great DIY. This could be a nice way to modernize the porcelain tableware of your great-grandmother. All you need is some tape to cover the parts of the crockery you want to keep original and paint or spray over the rest of the saucer. You could use some different tones of one colour, to avoid it from becoming too chaotic. I think this is a great way to personalize your wall in a colourful way.
If you’d rather don’t want to waste your family inheritance, of course you could find yourself some antique items at the flea market ; )
