Folded Greeting Card, Size: Standard, 5" x 7", Paper: Signature Matte, Envelopes: White
I was searching high and low for an invitation that went with a fire theme (account my mom wants 70 real live burning candles on the cake) surprise birthday party. I found these and couldn’t buy them quick enough! They far exceeded my expectations! One word of caution is that they default to matte so if you want glossy finish you have to manually select it. I only changed where the 2 clip art pics were located to make space for the text. I even used the default font for the design. Comes with nice white envelopes that don’t need the upgrade. The feedback from the invitees has been amazing. Thanks Cathy for an amazing product!! *please note I redacted sensitive information on the pictures with black mark out. .

This was my first time ordering from Zazzle. I was not disappointed! The card was amazing. I personalized it and that made it even more special. The amazing quality of the card was definitely noticeable. And you really can’t complain about the prices. Perfect. Clear. Not too dark, not too light. Just like it looked online.
