My parents used to collect plates, cups, etc. from Regout (see http://nl.wikipedia.org/wiki/Petrus_Regout). They covered the attic wall with the plates. It looked lovely. But now they lost interest in the project and they put it most of it in boxes. With special occasions when a lot of people come over, like Christmas for instance, some of it will be retrieved and used.
I saw a pile of bowls sitting on the sink and it looked lovely just beiing there with all the colours and patterns.
