I am thinking about sealing my invitations with wax. Michaels has all the stuff, you dab some melted wax on the envelope fold and then press this metal mold onto it that forms a beautiful monogram. It looks so cool and official. My fiance is only concerned about how well the wax holds up during shipping. He is afraid that it will look beautiful when we do it and then by the time it goes through all the post offices and mailboxes the wax will chip off some and be a crumbly mess. Has anyone done this technique before? how did it work out? I know there are the new stickers that mimic the wax seal design but I love the real deal. Please let me know! Thanks
