We are offering wedding cards. a invitation is a letter asking the recipient to attend a wedding. It is typically mailed six to eight weeks before the wedding date. Wedding invitations may be printed using one of the following methods: engraving, lithography, thermography, letterpress printing, sometimes blind embossing, offset printing, and more recently, on laser and inkjet printers as many do-it-yourself brides are printing on their home computers. Invitations can be ordered from an artist, or vendor specializing in invitations.
