My kitchen is done in red, white and blue. I have vintage wallcovering that has old fashioned water pumps, butter churns, flowers and butterflies. It is a creamy color with shades of brown for the items. I live in a rental so I'm stuck with it. I have red gingham curtains. I have blue cookware, blue and white dinnerware, and blue handled silverware. I have wicker baskets, watermelons, advertising tins, Depression glass, wire egg baskets and miniature quilts decorating the kitchen. My dining area and kitchen are combined. I use various themed table runners. Some of the themes are watermelons, cows, Christmas, Halloween, Valentine's Day, Easter, frogs and some are various colors of quilt blocks that I made into table runners. I use quilted, crocheted and knitted potholders and hot pads that I've made over the years.
I guess you could say that my kitchen/dining area is done with a Country Theme.
