There was just a scrap of this fabric left, not even enough to do both the front and back, just enough for the front of the pillow. And not enough of the solid linen I used on the back to do welting.
And because I dislike installing invisible zippers (well, that WAS true until I got an invisible zipper foot for my machine, now they aren't so bad,) I did buttons. I chose the abalone buttons from my vast collection. My client was happy and her love seat was happy.
