I used to think that the bias - the tricky diagonal thread line that cuts at a 45 degree angle - was reserved for a few random sewing pattern pieces, like a collar or an armhole binding. Little did I know that the gorgeous gowns of the red carpet rely heavily on the bias cut for form and fit.

Most garments are laid out along the lengthwise grain and sometimes the crosswise grain. The bias offers some stretch and paves the way to create sinewy lines. You may just appreciate this particular sewing technique from ogling beautiful gowns at awards shows like the Golden Globes, but it can easily be incorporated into basic items as well.

One of my loveliest creations is an ivory satin gown cut on the bias. Special occasion gowns are costly to buy and not really that difficult to make, especially a basic bias pattern. Most sewing instructors will start a beginner with pajama pants, but I say that a simple evening gown is just as easy and a whole lot more inspiring.

(Note to all glamazon seamstresses: be sure to hang a garment cut on the bias for at least a day before hemming it.)
