I have just been standing in my shop talking to my sign guy about doing this kind of thing for the shop. There is a similar company www.wallwords.com that does - words.
He's going to price some things out for me. Want to offer 'sayings' etc. to brides. You could customize the church, or reception site with the Bride and Grooms names. Lots of ways to use them. Going to see if my local guy can offer it cheaper.
