Like that sofa, Teyon.

Hey clarkie, what's your method for modeling pleats? If you don't feel like answering s'okay... just that I noticed and it's somewhere on my 'to learn' list. Just off the top of my head I would lathe something out, cull some polys, and reshape the one sided geometry but that's just a quick guess. hmmm, maybe an array with bridging? Anyway...

Edit_ extrusions with tweaking?
