Baby nursery wallpaper borders are no different than any other border. It’s just that borders created specially for nurseries may have been printed with pictures of baby gear rather than other less infant oriented designs. It’s possible to find wallpaper borders whose use may not be exclusive to a baby’s room, but that will fit with your chosen theme or style of nursery decor.
You will go about the process of selecting a nursery wall border the same way as you would choose a decorative wall treatment for any other bedroom in your home. Begin by hauling your baby bedding fabric or whatever baby accessory that you need to match down to the store, buy enough yardage to make your way around the circumference of the nursery, hang the border on the walls and voila your job is complete.
