1 You can't use \include inside a file which is read by \include. 2  This is by intention and is because to avoid issues with the .aux files. 3  Otherwise three .aux files (main, parent \include, child \include) would be open at the same time which was deemed to complicated I guess.
Timing the Invitations. It is customary to mail your wedding invitations about eight weeks before your wedding date. If you have already mailed your save-the-date cards, then your wedding guests will be expecting your actual wedding invitations in the mail. The process of choosing your wedding invitations and preparing them to be sent out can be time-consuming so it is important to not procrastinate and allow yourself plenty of time.
Hi and congratulations: Most wedding invitations are mailed (or should arrive at the guest's home) 6-8 weeks before the wedding, not necessarily 2 months, but that is OK also. Shower invitations will not be mailed by you, but by the person hosting the shower. Shower invitations only need about 3 weeks notice.
