I am trying to put a sb/autograph book together for each of my children. It was suggested to me on this board to do tags for the autographs. I'm using 7x7 books. I started to play with making the tags and was wondering, how small is too small? I'm just worried if I make them too small, the characters won't be able to fit their signatures on them. On the other side of the coin, I don't want them too large, since I'm working with the 7x7. Any suggestions?
