The February/March column is about fly-front zippers. If you want to try out the technique but don’t have a fly-front pattern, never fear! You don’t have to go buy a new pattern (unless you want to, of course — who doesn’t love an excuse to get a new pattern?). Turns out that while it’s always best to use a pattern designed for a fly-front zipper, adding one to a pant pattern that has not been designed for one is easy. To do so, follow the steps below.


  • Pants pattern without a fly-front zipper
  • Pattern or tracing paper
  • Curved ruler

Tape tissue or craft paper to the pattern center front.

This will vary based on one’s size, personal fitting adjustments to the front and the style of the pants. Typically, the base point is located anywhere from 2” to 4” from the crotch inseam intersection. There should be enough space to accommodate a 7” or 9” zipper. Once determined, mark the point on the center-front line with a square dot.

Add the flap to the tracing paper by drawing a line 1 3/4” from the center-front seamline that curves to the zipper base point, using the curved ruler to ensure a smooth curve. This becomes the new cutting line for the fly front.

Cut out the new pattern piece and construct the fly front.

Wasn’t that easy?
