I found two napkins on clearance at Target after Christmas last year for super cheap. I placed them, right sides together, and sewed around three sides.
Then I pulled some white ribbon from my wrapping paper bin and sewed two pieces onto one side. If your sewing machine has a button hole function, you could use that, but I just used scissors to cut a slit/buttonhole in the other side.
Turn it right-side out, stuff with your favorite pillow form, and tie the bows. Voila! Super simple cloth napkin pillow. Think of the endless possibilities that cloth napkins as pillow cases can do! Every season! Every week!
