"On the whole [the alignment of a series of stained glass windows with the interior of a villa in The Hague] I have thought about all the time.. .I want to focus more on the architecture of the interior in general and that should we do together [with architect Buys].. .Now I was already thinking, the enormous color effect that the window will generate - and that will certainly become powerful - must be accompanied with strong colors - the hall -, otherwise the window itself will be too much isolated. For instance the staircase, could it be painted in strong colors and not [in] oak.. ..deep ultramarine blue or green, with a beautiful colorful carpet.. ..I feel I must make designs for carpets, to create in that way a beautiful unity with the stained glass as a whole.
