I'm not a huge fan of it, because texturally, it's very different than a solid surfaced wall (although Eggy ingeniously made some flat walls in that example so there was some consistency). But the approach shown above from Flickr has a different pattern to the surface as well, and it's limited in what size circumference you can make, so it's a matter of your tastes, and what technique will actually function best with the space available to you in the MOC.
I also have discovered another technique that I've not seen done before (although it probably has...nothing's new in LEGO!). But I'm actually going to be a greedy little slob and keep it to myself until I get around to building a castle Mmmwwwaaaa-ha-ha-ha! (Yes, JD...I've finally got plans to do one as soon as I finish the Eye of Chaos SHIP for Brick World). I'll post a "how to" once I've done the castle, but it'll be a while. Permalink
Quoting King Borether
...did peasants live outside of the castle?
First of all - sorry if I'm butting in. Second: Well it would really depend on the castle - Most castles were the property of nobles, dukes and kings, people in "High" society. If they wanted a peasant to live in their castle, then they would allow the peasant. On most occasions nobles were very criticizing of those who were "below" their level of wealth and would turn their noses up to those who shovel the stalls. So - most likely - peasants would live outside the castle walls. If you're talking "Fantasy" style castle, do what you want. That's the pleasure of fantasy! Permalink
