Say wallpaper borders and you conjure up images of twee florals or cutesy bears – not the sort of thing we’re known for featuring on BG. Well, these borders from French company The Mark on the Wall couldn’t not be further removed. The borders (available in four designs) were created by Anouk Ricard, measure 53cm x 5m and come in ready-to-colour black and white in a tube, complete with wall adhesive. A great way to add interest to a plain painted room, without committing to a patterned feature wall. Â£40 per roll, The Kid Who.
