To me,
words + wedding + quilt => embroidery
I quite enjoy hand embroidery. You'll be surprised how quickly you could stitch it up.
I would draw/write it out, then stitch all in the same floss. Probably one with just a slight contrast to the background fabric. Maybe you could find out the wedding colours for your fabric and floss choices?
You could emulate the wedding invitation by enlarging it.
Then use that to trace from, over a light box.
ha! .... looks like as I was typing you were thinking the same as I,
Tartan!
