"This save the date in blue is bright and beautiful. The only thing that I noticed is that anything printed over the picture in the bottom left corner can be slightly difficult to read. The blue color is vibrant and the magnets are of good quality"
"Thank you Wedding Paper Divas!!! You guys took our ideas and turned it into exactly what we wanted. Our wedding colors are ivory and navy blue so when you were able to change the color of the text to navy blue, our Save the Date Cards were spectacular! What was even more amazing is that I spoke to customer service within 3 minutes of being on the phone. When we talked you gave me suggestions, then had the proof done by the time we got off the phone-thank you!"
