I trace all of my LH patterns--I use them often and like the Sweedish Tracing Paper for most patterns. I have made many pairs of European Pants and a few less of the Oxford Pants. My traced patterns are already shortened to fit my leg length, scooped to account for gravity of the posterior, and generally dependable to produce a pair of pants I can wear without alterations.
So--Loes recently gave directions for modifying the Oxford pants to make them from a woven. Not much change, but a zip front accomodates the need to fit the waist over the hip without have a lot of bulk at the waist. I have done this in the past to the cruise pant with success.To do the Cruise version, I put the European front pattern over a Cruise pattern and retraced the entire front. When I was reading The Look publication recently, I had an "ah-hah" moment! I came up with the following clever/lazy method for altering any LH pant pattern into a zip front!
1. I traced the top ten (or so) nches of the European Pant front
2. I got out my previously-traced Oxford pattern
3. I placed the short piece of the Euro pant pattern on top of the Oxford pant front
