I didnt see any mention of invitations. As these usually take awhile to either print or make your own, you probably need to get those underway. You don't want to wait til the last minute to mail them out.

I wouldn't necessarily be buying food just yet if you are fixing it yourself, but I would certainly have my menu planned.

If you have your wedding and reception site booked, I would be getting the photography, DJ(if having one) and cake ordered too. Also start looking around for idea's a sales on centerpieces and decorations.

Best of luck!!!
