I'm not sure who the castle belongs to...I would love to give them credit because it isn't mine, but I wanted to help you out with your request. Is this what you were wanting? I wasn't sure what color or where you wanted the placement of the writing. I could do it in a circle around the castle if you wanted and change the font. Just let me know. Hope your anniversary is great! Again sorry to the DISigner of the castle for not giving credit where credit is due.
Another image that might work for you is in Natalie's shared file under weddings...she has interlocking gold wedding bands in the shape of mickey heads. Just an idea for you.
