Plains, the selection of fabrics that don't have any print or pattern, just plain weave and in arrays of colors. I like to work with plains, it is like a box of crayons, a paintbox or color charts. Whenever I see a book of fabric swatches of all the colors I want to use them all.
The trick of using all the colors is keeping them in the same tone, no color brighter or darker that the other. They look very good in family rooms, in a bright and funky restaurant or children's room and make the space lively and fun.
This past season of plains from Manuel Canovas was a great selection.
