This is letter I designed for my friend. Both types of paper and the ribbon was from Michael's craft store. I did have the initials of the recipient written in calligraphy on the empty red section, but I removed them, as the recipient does not wish to be known. :)
I wrapped the ribbon around the envelope after I put the letter in. :) I just fastened it with rubber cement a couple of places to hold it together, and sealed the ends together with a wax seal. I got my wax sealing kit online from Gartner Studios, but you can get them for a better price online at Kohls.
Have an awesome day!
