Very cool, and I love it, but the "aged parchment" background is not quite what I was expecting. I knew it would not be real parchment, but it looks pretty artificial to me and therefore a little cheap. I don't think that will be too noticeable if you are not close-up, though. I wish I could have seen close-up images of the different background options ahead of time to avoid this issue.
