One thing that was really important to me when looking for items to add to my registry is sustainability. While we will be using and registering for some easy and cheap things, I also want to start our married life as green as possible. Also, the point of a registry is so that you don’t have to go out and buy all these annoying little home-building things. And thankfully, sustainable and reusable items often eliminate the multiple trips to the grocery store to do just that.
