In the past I've quilted fabric I want to use to make covers for all my toilet seats. As for pillows, I got into doing pleats on my pillows to add a little texture. I pleated a complete WOF until I got to the center and left that blank and it fit perfectly for my pillow shams to go with the quilt I made.
When I was making cushions for my porch swing and wicker chairs, I put the fabric on the machine and quilted it fit. Sure makes them look high end with that added touch.
