"Very nice cards. I have NO complaints. I thought they were going to be bigger but its a nice size just to say thank you to our guests."
"We love these Thank you Cards we ordered for our wedding, The design was simple and perfect for what we were looking for. The only thing I would suggest to the site is; when your editing the card (putting in Initials) the program only lets you move it "K" & "D" in three spots, would be nice if you could just click the letter you want to move and freely move it into the exact spot you want. the two/three spots it lets you choose are either too far right or too far left... nothing looked centered. But it wasn't a deal breaker with this purchase, we still love them. and the shipping was excellent. I received and email saying they would be shipped within 24hrs and I had them in my hands the NEXT Day!"
