For the first pillow, I used plain red fabric with one of my favorite vintage buttons for the front and a black/white tweed with a plain red fabric button for the back. The red was formerly a curtain, and the tweed was formerly a skirt.
The second pillow has the same tweed on the front. The buttons (from my collection) have holes at the top instead of in the middle and are attached with yellow thread to match the fabric on the back. The finished pillows are 12 x 12.
