The first step is thread tracing lengthwise and crosswise grainlines in the original jeans.
Seams, pockets, yokes, every feature is thread traced to make it easier to copy all needed information from the garment. (This method can be applied on all garments you want to copy, not just jeans).
I forgot to make an overview picture, but the jeans in the picture below shows the tread traced lines:
The information is first transferred to silk organza, from there to paper. Voila!
The pattern ready and cut out.
I did some test runs for the topstitching. I did not want it to be very contrasting so I just used a double thread in a color that matches my fabric. Here is one of the backpockets. I have some cleaning up to do, lots of threads to pull to the backside and tie together for a neat finish.
That's as far as I got. Some emergency apple picking due to storm forecasts changed my further sewing plans. This weekend I'm off to Amsterdam to enjoy a ballet performance, back in the sewing room on Monday!
