A big thumbs up for this local business. They're just by the (closed) Shell garage on Southwark Bridge Road. I had a tender that I needed professionally bound. I went in there and the the guy really went out of his way to explain the different methods and explained all the equipment he has. They do all sorts of printing and binding - photos, canvas, etc. They did a first class job for £5-something on thermo-binding my tender.
Seconded. Have used them twice in the past, once for a thesis binding and more recently in a blind panic on the way to the airport when I needed an easyjet boarding pass printed (because, you know, mobile boarding passes aren't a thing Stelios...), and they dealt with both scale of jobs very efficiently.
