The home of Carl and Karin Larsson is "an icon in Swedish home decor and family life". A visit, or perhaps it should be called a pilgrimage, was made last week to see the settings for Carl Larsson's colourful, affectionate, almost photographic watercolours of domestic life. The tiny village of Sundborn has become a magnet for tourists but, happily, the house, its interiors and surroundings remain instantly recognisable from Larsson's images.
