"My fiance and I selected this enclosure card to list accomidation options for our destination wedding in Key West, FL. We ordered the sample in the basil color first and thought it looked great, but decided to change the color to Bay to fit with the rest of the colors we are using for our wedding. The paper that the cards are printed on is a nice heavy card stock and custom color came out looking beautiful!"
"I liked everything about the product. The "milk" color font is not as ivory-like as I thought, but all in all, nicely done cards."
"I love how I was able to personalize this card to include information on our wedding gift registry. The black was not as deep or rich as i expected but the matte was interesting."
