I was looking at our invitations today and I realized we may have made a small mistake. Luckily, not a typo that would require us to reorder them all! On our response cards, we used one of the samples online and it looks like this:

The wording just asks for the Names and Number of Guests. I didn't notice until today that response cards usually have a line below to check either "will attend" or "will not attend". Doh!!!
I have tested out and I can add those lines below on our printer and match the color and font almost perfectly. However, you can tell if you look closely that it was added. FI thinks no one will notice and it will be easier for guests to add it. What do you guys think? We'll probably add it, but it bugs me that it isn't perfect. If we were to leave it the way it is, will it be confusing to guests? Like, will they put 0 for number of guests if they can't make it?
