Some time early in lockdown we decided the house needed to reflect our tastes more. The walls were still the same boring magnolia they were when we moved in. 

After a few sketches I came up with these as the general layout for the living room wall - which is approx 7m x 2.5m.

I bought some tins of Graphenstone ecological paint in ebony, pewter, indigo and white. I had been hoping to find a more purple colour but settled on dark blue for the sky.

I used standard decorator's brushes and rollers.

The tins were all 0.75 or 1 litre and I used at most half of the paint.

To transfer the image to the wall I sketched the major components in pencil after marking out 1m marks on the skirtingboard. You can see the equivalent marks on the sketches above. My scaling wasn't quite accurate and I found I had much more space on the wall than I had planned for, so I moved and added some elements.

It was tricky taking a photo from far enough away to get it all in and without bits being covered by furniture, but here it is!
