The best way that I've found of finding people to draw is to sit somewhere that people tend to congregate and wait a while. There's quite a few of those in London.

One of the best places to find people sitting and taking a "time out" is on the steps in front of St Paul's Cathedral. Here's my sketch of people sat on the steps and done while I was sat at the top of the steps waiting for fellow Urban Sketcher Liz Steel (Liz and Borromini - from Sydney Australia).
Did I tell you how Urban Sketchers is also a great way to meet other sketchers from all over the world?
