Some designers feel that one of the best ways to create a cohesive look in a small space is to repeat the same print throughout. I recently found these photographs of the late designer Greg Jordan's apartment, and I think he certainly adhered to this tenet.
Jordan's apartment had a living room that was 13' X 16' and a bedroom which was 10' X 15'- rather small. Jordan's solution to making the space seem larger was to use the same fabric on everything- walls, windows, upholstery, bed. By employing this scheme, the boundaries of the room seem to disappear. The fabric he chose was of his own design: a chain-link fence print. Obviously done tongue-in-cheek, Jordan wanted to create an "urban version of those eighteenth-century English trellis patterns."
To me, the effect is not necessarily overwhelming. I think that the other objects in the room- books, antique furniture, and other bibelots- soften the severity of the chain-link pattern. They also seem to take center stage against this unified background. I actually find the whole look rather charming.
That said, I don't think this look is for everyone. You would have to make sure that the print you choose is one that you love (and one that you will love for a long time!). Also, might one feel claustrophobic being surrounded by one print everywhere? In a quest to "eliminate" borders might you feel a bit caged in?
