Of the many blogs I am obsessed with, one of the best is called A Cup of Jo by Joanna Goddard. She also posts on Glamour's relationship blog Smitten. She is getting married soon so lots of her posts are about weddings! She just got her engagement photos taken and I LOVE them. I think she has more on both sites.
On the Smitten site she also shows a couple of ideas from another couple - the first is a Save the Date card they made by adding to one of their engagement photos. They were actually lying on the grass for the photo!
