Considerations
The width of the cloth helps to determine the length of the trousers. It is possible (like most of these patterns) to rotate them 90 degrees, with the trousers however having flexibility across the body is more pertinent. Unless your fabris is the same on both sides you will need to make two pairs.
Recommendations
The drape or stiffness of the cloth will alter dramatically the final look of the garment. For a fluid drapey look, go for a knit, crepe de chine, or other soft fabric, for something more architectural chose a stiffer fabric such as a denim.
