1. Baste the fur piping trim to right side of one of the 18" edges of one of the lining pieces.
2. Lay the piece face up on a work surface.
3. Place the 12"x18" matelasse piece face down on the basted lining/fur trim piece so that the right sides are facing and all of the raw edges are aligned.
4. Pin along the top edge (the one with the fur trim). Using a zipper foot, stitch as closely as possible to the fur trim to secure the pieces together.
5. Turn the pocket right-side out and press.
6. Lay the 18"x18" matelasse piece face up on a work surface.

8. Stitch along the pinned sides to baste the pocket to the square piece.
9. Set assembled panel aside.
10. On the remaining lining/backing pieces, finish one of the long edges of each with a narrow hem by folding under the edge 1/4" and pressing.
11. Fold under an additional 1/4", press, and then stitch to secure.
12. Place the assembled front panel face up on a work surface. Place one of the back panel pieces on top of the front panel piece, facing down so that the narrow hem runs through the center of the front panel piece and the top two corners and all raw edges are aligned. Pin.
13. Arrange the remaining back panel piece on the lower half of the pillow in the same fashion and pin.
14. Stitch around the entire pinned perimeter of the cover with a 1/2" seam allowance, increasing the stitch length as needed when stitching over the fur trim.
15. Clip the corners and finish the seams before turning the cover right-side out and placing on the pillow insert. Tie a bow with the grosgrain ribbon. Use a needle and thread to hand stitch the bow to the front of the pillow pocket.
