I once did one for a couple I didn't know well. I did a machine embroidery of a bride and groom on off white satin. I added applique flowers (the ones you bou to add on to clothes and wedding dresses). On the top I did an arc with ribbons, held at the very center by two plastic little doves and at the end of each ribbon, a little plastic wedding ring. I added their names and wedding date at the bottom. It took me about 4 hours to make including the machine embroidery time, and the only bad part was that I didn't take a picture of it.
