I also made this banner I saw at jenniferrizzo.com (for some reason I can't link to her post). I took the easy way out and didn't do grommets. I added another layer of paper to the back so it was strong enough without it. The grommets give a much nicer finished look. When I got all finished and hung it, I realized that it should have been smaller for this spot. Oh well, it was fun and I will probably find another place to hang it.
It is December now. Time to stop playing and get to work!
