It's only fitting to present the symbols of a new union on a beautiful "something old": a pillow embellished with an heirloom handkerchief or another vintage linen. A few stitches keep everything in place and can be snipped later. If you don't have a vintage piece, you can find one at a flea market.
Place the pillow on the wrong side of the linen; fold the corners in, overlapping them.
Hand-sew the middle of a satin ribbon to pillow center, sewing through the linen's corners and pillow; use two or three stitches (when ready to remove linen, cut the thread). A few stitches in the center will also secure a small doily or cocktail napkin to the pillow's top.
Or you can make the pillow itself from vintage fabric. To attach rings, thread them onto the ribbon and tie a bow.
