Met my expectations perfectly. Quality notebook with lined paper. Good size and good amount of pages. I used my own design and added the birds. Color of scenery was beautiful and dark printing exceptional with the light background.

The print came out beautifully and the color wreath was bright and vibrant. I gave it as a gift for Mother's Day and my mom loved it. The customization came in key and Zazzle has plenty of customized type (and symbol!) options - really great cover! Printing was great!! Wreath was bright and vivid like the photo!
