With our first anniversary rapidly approaching I started gift brainstorming awhile back. The traditional gift is paper, and the possibilities are seriously endless.
Another thing for the walls would be a custom print of your wedding vows or readings from your wedding.
Books if your Mr. is a reading man
For him or her custom monogrammed stationary
And really, anything could be considered a paper gift if you give a gift certificate... or you give papers saying what you got them. My gift was a new fridge, and I was handed the rebate papers.
Have a ton of money? Go ahead and just get mortgage papers for your anniversary gift.
