One product I have to recommend is ”my wedding planner” by myweddingplanner.ie.
The book is divided into twelve months with each month having a checklists and a few pages to make notes. It is a great resource as it is focused on Irish weddings.
I use the book in conjunction with excel. The book is handy to have if you are away from the computer, out meeting suppliers or at wedding expos. The book has 80 pages and is in A5 size so it fits nicely in a handbag.
You can order the planner from their website and it costs 24.45 including shipping via fastway couriers.
