A potentially exciting new publication on sketching from James Hobbs, a regular contributor to Urban Sketchers (in the UK). I say"potentially" only because I haven't seen the book in my hand, but I hope to soon.
Fascinating inclusions are listed on Mr. Hobbs' website of many artists work I have never seen and many artists I hadn't heard of before--that in itself is the most exciting to me. Thus far, I've opened and viewed about 1/3 - 1/2 of the websites and eager to see more.
