¿Qué idea tienes, qué estilo te gusta para tu stationery?
If it seems appropriate and not too busy, I wouldn't mind having the type of images that are on my website, as some sort of backdrop I will upload images. Use what fits best. This could be EITHER on the front or back or BOTH if the design warrants it
however, I don't want the site to look busy. I am looking for clean and elegant.
