I personalized a mug for my mom as part of her Christmas present. It included a photo of the two of us and a personal message. She said the message made her tear up on Christmas morning (happy tears, that it). She used the mug for her coffee that same morning. I recommend following the photo quality guidelines that the website provides. I wanted to be sure that the photo was clear and proportional, so I took some time to adjust it to the optimal dimensions before uploading it to the website. It turned out great!
