I converted this wall set for Alannis like a month ago but didn't share it publicly because I was too lazy to make a preview picture.

I'm still too lazy to make a preview, but I wanted to share the walls because maybe someone will find them useful, so I just used Donnha's original pic

download (both sims3pack and package included. aside from the original uncastable recolours, some walls are fully castable.)
