No matter how hard I try, I cannot make two pairs of jeans that are identical.<p>Same pattern, same denim, same person making them (me), they don't fit/feel the same.<p>Consistent results when using fabric is hard. Also keep in mind that good denim is practically sheet metal in comparison to most fabrics, so on one hand easier to get consistent results, but on the other hand, even small differences are more noticeable than something lighter or (god forbid) stretchy.<p>You cannot just engineer your way out of some of the challenges inherit in garment construction (trust me, Ive tried).
