Don't worry too much about it, I'm sure she'll be okay with it. It's just generally best not to make assumptions, ask first and you're set. =)
Hopefully that'll help - I don't remember the paper being very big (unless they just cut it up when they gave it to us, haha), nor did I know you could print onto them. Should have figured, though.
