You've lost your planning Mojo as JQ would call it!!!! It happens to all of us I think, the head count thing is a real downer as you just want to know how many to plan for!!! Keep your chin up, you will get your mojo back!!!!!
Congrats!!!!! It is a big sigh of relief to have the big things out of the way!
I have a file called "wedding" on my computer in there there is a ton of sub files, I save a LOT of pictures that inspire me ie. centrepieces, aisle decor, cakes, etc. I also have a word document with notes to myself in regards to the forum and ideas that don't have pictures or something "-check out Bride's Planning thread" It also helps to subscribe to threads that inspire or interest you that way you can refer back to them closer to that stage!!! Good luck!!!!
