This type of support was a surprise and began by pure chance. I still remember my son who, coming back from school, handed me 3 3x12cm bookmarks made of 1mm thick plywood and said to me “Dad, the teacher gave them to us, they are made of wood and I don’t know what to do with them but as soon as she gave them to me I thought of you because I believe that you’ll come up with something.” Indeed my big mouse was right.
