But unfortunately we live in rather small flat, without too much hope for a change at the moment, so there is no space for another desk just for a painting station.
Finally I decided to buy at least a shelf to keep some stuff closer. And that's the result (of course some rearrangements on the shelfs will happen in the process):
As you can see Bombel the Inspector is rather pleased with the new arrangements and claims the bottom shelf for himself. I must say, I was hoping that he can squeeze his furry ass in half of the shelf, maybe even 1/3... but it was vain hope as as presented above.
