I understand you very well and you did a great job André!
Last year, I had a new "staircase" built in my garden ( the old one was completely ruined and you could hardly put your feet on it and I always was afraid to walk with full plates of food. This new one is super nice !)
I have no idea why only one minimodel has cavities
Sometimes, it`s difficult to decide whether to keep variations or not, because..take a look at the minimodels Johann
They can be so nicely different, right?))
