I don't know if it will be engagement pictures when they roll around, or a family portrait session 10 years down the road, or what. But, I will do something just like this at some point, or my life just will not be complete.
Me, my loved one(s), and a few overstuffed feather pillows. It doesn't get much better than that.
And, now that I think about it, I think this would be absolutely PERFECT for that day after the wedding trash the dress session I've always dreamed about... file this under "major inspiration" and "must do in order to die happy".
