More about "Denim Fabric"
The name denim is derived from the french town where it was first produced, Nimes: 'De Nimes'.
Denim fabric is made using dyed warp threads, (vertical thread), usually in the an indigo colour, while the weft threads (horizontal threads) were left undyed. This is why the inside of jeans and other denim products often have a much lighter appearance on the inside. This use of two different colour threads gives denim its distinct fading quality as it wears.
