The second thing you should do is decide what exactly you want to DIY. What matters to you the most? How tight is your budget? How crafty are you and your friends? If you are having a small wedding perhaps hand writing all of the invites would be a great and personal touch.
When you figure this out make a list of things you want to DIY: at the top put what you really want to do and work your way down. Talk to your helpers and see what you thing is feasible
When you have your list of DIY projects make a timeline of when everything needs to get done:
- Save the Dates
- Invites (plus any inserts-maps, directions, response cards, etc)
- Escort Cards
- How to display them
- Favors
- Programs
