I did it again. And not alone this time! M helped me to start and I enjoy to continue. Tu put a puzzle together gives me peace of mind. Somehow, I put my will of order in the search of the right piece for the right place and find s big satisfaction in finding exactly the right.

This puzzle is particular: it is in 4D, meaning that we have two layers, one of the 17th century and one of now plus buildings which where build at different times. And the model is Paris, which makes it even more interesting.

The only negative thing is that we started it on the kitchen table and since we are having some visit this week end, we need to finish before.
