Bar Tacks - Vintage Levi's Jeans Guide

Bar tacks are a sewing process that was used to reinforce the top corners of the rear pockets of jeans.  It involves sewing a large amount of thread to an area for strength.  It can also be used as an 'acid test' to whether or not Levi's are vintage or not.  If they contain bar tacks at the corners, you can usually say that those Levi's are at least 20 years old and may be vintage.
