There are two dimensions to whether the design is postcard or bookmark format:
Postcard: 110×156 mm
Bookmark: 85×200 mm
Designs are closed models, so you can only change its color. The typography and composition of these cannot be changed.
In case you want to add a custom logo, for instance with our initials, you will have to notify the designer in advance and provide the file in vector format (.ai, .eps, .psd, .pdf).
In case of doubt, please feel free to contact our designer; she will be delighted to help you!
