Of course I have no pictures handy, and I am NOT any sort of sew-person or tailor (although I play one on TV ), but when I look at the selvedge on my tank the only way I can describe it is that the fabric just "stops". The material isn't folded, there is no strange looking pattern for a quarter inch or so-the weave just neatly stops (well, perhaps it seems slightly 'bumpy*).
