Something really simple and easy would be to decorate picture frames. It's as simple as going to a dollar store and picking up some inexpensive wooden frames. And then going to Wal-Mart and buying paint pens & paint. You could paint them white and then write your motto at the bottom. A Joann's the normally have small painted wood shapes, if you could find rose ones, you could add those too.
Some thing that is incredibly cheap to make are pin pillows. Buy a few yards of flannel and some filling. Cut out a bunch of 2.5x2.5 inch squares, sew & stuff 'em. It's really easy and inexpensive. I just did this. I spent 8 dollars and was able to make 20.
There are a bunch of ideas in this thread as well:
