Seeking terry-cloth trim

I've been looking for terry-cloth trim in preparation for making a new bathrobe.  I need a continuous piece a bit less than 3m long, either 8 cm wide single-sided nap or 4 cm wide double-sided.  Preferably white, though I'd consider some colours.  I've tried the fabric stores near my home without success.  Is there some store in the Ottawa area which is likely to have such a thing?  Obviously, I could just buy a 3m length of fabric and use one strip of it, or join shorter lengths together instead of using a continuous piece, but these solutions are non-optimal.
