The last couple of years I've somehow managed to incorporated mitered pillows into all of my design projects. I love taking a striped fabric and making a great mitered pillow, they look great mixed with solid and print pillows, plus they're just fun!! You can miter the fabric to resemble a "box" or create a "cross" pattern, either way striped fabrics can make mitered pillow unique. Here are a few examples of great mitered designs.
Love the mitered ottoman!!!
Here is a great design made from a striped fabric!
Here are a few of my own designs (photos do not do the pillows justice!)
