In the domestic sphere she popularised the use of tapestries and carpets – the use of hangings and especially floor coverings was noted as a Spanish extravagance on her arrival in London, but by the time of her death was plainly much in vogue amongst richer magnates, with certain of her hangings having to be reclaimed from Anthony Bek, the bishop of Durham. She also promoted the use of fine tableware, elegantly decorated knives, and even forks (though it remains uncertain whether the latter were used as personal eating utensils or as serving pieces from the common bowls or platters). She also had considerable influence on the development of garden design in the royal estates. Extensive spending on gardens is evidenced at her properties and in most places she stayed, including the use of water features – a common Castilian garden design feature, which was owed to Islamic and Roman influences in Spain. The picturesque Gloriette at Leeds Castle was developed during her ownership of the castle.
