An interesting link posted on Ravelry about how knitting stretches

However, the first illustration is a brilliant example of knitting that isn't quite symetrical, ie slightly more tension on one side of each loop.  It's the sort of thing that's more likely to happen with fabrics knitted as a tube and then cut open (weft knitted single jersey).  This is the reason why so many tee shirts twist.

I always though that t-shirts twisted because they'd not been cut on the grain properly!

If the lengthways and widthways 'grain' isn't at 90 degrees to each other it's impossible to cut pattern pieces true to both grains.
