Hi, I was wondering if the response card for the rustic peony and deer antler invitation could be customized. Id like to remove one of the boxes and add a line at the bottom. I'm unable to do this on my own through the zazzle website, nor with the help of zazzle customer service. Was told to contact you through the comment section. If you can do so, please contact me by email: firstname.lastname@example.org. Thank you!
