Pretty wedding bells in satin appliqued on? Narrow satin ribbon tied in bows on the bell(s) and linking one to the other around the invitation. Champagne glass, wedding rings? Or, white satin gimp braid and beautiful lace forming a frame around it, ribbon roses in the corners. I use to make wedding albums, and you can buy beautiful trims that work great, pearls, sequins, different styles of lace trim, whatever suits your fancy. All glued on! If you are doing a photo fabric, maybe cover the photo with a layer of tulle to soften , add some batting to the back, glue those trims on and put in a crystal frame.
