I've taken a break from the Funky Flower throw for a few days. I need to back up and punt.
Several months ago our quilt guild made pillowcases for Erlanger Children's Hospital in Chattanooga TN. Starting with 1 yard each of two coordinating fabrics, I cut 9" WOF from each piece. I used this 9" strip to make the cuff on the other pillowcase (and vice versa). You'll have matching pillowcases, but each is unique. Each pillowcase has another fabric (2"-2 1/2" strip cut WOF) used as piping.
