I was recently commissioned to decorate a wedding invitation.  This is the second time I've done this and I think it's such a wonderful gift idea.  My client provided ideas for imagery, all meaningful items like the location of the engagement, the location of the wedding, the wedding flowers.  Then I created the design to frame the invitation.  She wanted a soft look so this is an ink drawing softened with an acrylic wash, then colored with colored pencils.  I fuzzed out some of the text to protect privacy, but you get the idea.  :)
