And just on the light [parts in the painting] here and there a small push of thick [paint].. ..thick house-interiors are unpleasant - long drawing before you start and arrange pleasantly together all things before you start to paint - if the money does not bother you, it is always useful to visit Rott. [Rotterdam]. (translation from the original Dutch: Fons Heijnsbroek)”
