The house is the house of marriage & relationships/partnerships (could be business partners as well) & as such rules this area of our lives. Your house is in Cancer (violet, sea green, silver) & relationships are done in a CANCER way.
I like the idea of an aztec throw in the living room. An eclectic mix of throws would be nice. You could display them on a rack in the winter to make things warmer and cozier and put them in a basket during the warmer months.
