I haven't gotten a chance to read the books yet, because my library is bizarre and for some reason only has The Twisted Sword, but once I get to college, hopefully I'll have much readier access to them.
Anyway! I've made a few (only a few, but I will make more) LJ icons of the series, using some of the images at http://www.poldark.org.uk/. Hopefully, they will interest you. Working in monochrome is a liiiittle difficult for me, but it's good practice.
I'm sorry, I thought there were more! Well, more will follow, then.
Credit is nice, comments are nicer. ♥
