  How to write an invitation
Step 1
before you write an invitation; decide on the tone, voice and level of formality, based on the event itself. This will dictate whether you hand-write the cards or have them printed, and whether you choose A preprinted or personalized invitation.
Step 2
Choose the type of invite you want, and order or buy a few more than you think you'll need. This will permit you to add some guests to your list at the last minute, if necessary. For small parties, you may want to hand-write the invitations on stationery or blank cards. For large gatherings, consider ordering printed invitations.
Step 3
Determine the wording of your invite based on the level of formality. For example, a formal invitation might say, 'Dr. and Mrs. Stanley request the pleasure of your company,' whereas a more casual note might say, 'Please join us.'
Step 4
Include the names of the host and/or hostess, as well as the place (with street address), time, date and purpose of the occasion, even if it's a simple get-together.
Step 5
Make sure to add RSVP information at the bottom of the invite if you need to know who will be attending; for example, 'RSVP' followed by your telephone number.
R.S.V.P. stands for a French phrase, "répondez, s'il vous plaît," which means "please reply.“The person sending the invitation would like you to tell him or her whether you accept or decline the invitation. That is, will you be coming to the event or not?
Step 6
Include a respond-by date on a formal invitation so you can get an accurate head count in time to adjust the amount of food, number of place settings and room size. For a wedding, charity function or other formal event, consider including a response card and a stamped, self-addressed envelope inside the envelope containing your invite.
Step 7
Mail invitations three weeks before most events, four weeks before a formal affair and three months before a wedding, to allow for airline reservations. For events held during the December holidays, send invitations around Thanksgiving.
