All the technical information necessary for shifting a dart into the seam of a pocket for the tailored jacket base pattern are provided in this file. Start from the front of the tailored jacket and learn how to create a shoulder strap seam that will extend down to a horizontal seam below the waist. The pocket will be created to hide this horizontal seam and this technique allows the straight grain fabric direction to be conserved for the side front panel as only the bottom part of the jacket shifts. The written and illustrated instructions to follow are clear and precise for a full understanding and top-of-the-range result in the size of your choice. This new base can be used to create lots of different models as well as the one described in the file. Develop your model further by using the following files in parallel with this one: The technical file of the tailored sleeve base pattern The technical file of the puffed sleeve The technical file of the tailored collar The technical file of the shawl collar.
