Instead of using a board or plaque, I used an old picture frame. I also used one inch wooden circles you can get at any craft store, and jewelry wire.
I mod podged scrapbook paper on the inside of the frame (btw the glass was already broken, but I would have taken it out if it was there). I used sticker letters I also found in the scrapbook section.
The circles were actually easy, I just painted them and wrote the names and dates with marker. On the back, I hot glued an inch long piece of wire, then bent it over to make a loop to allow the circles to hang on each other. The circles are also color coordinated to which side of the family the person is from. :)
