I first learned to pattern draft pants in wearable forms in my third year, but it wasn't until I went to Sweden that I really learned the process for drafting pants. If you ever feel the need to make some pants I would recommend that you consult Patternmaking by Dennic Chunman-Lo for womens wear and Patternmaking for Menswear by Gareth Kershaw . The books help you determine your measurements and use them to create a draft from scratch.
I made a basic pant draft using Chunman-Lo's instructions and what I remembered from classes. From there I went through about five different patterns before settling on overalls as the final form. In Fig.2 you can see the completed pattern pieces for the overalls.
One of the new skills that I learned while creating this pattern was how to add pockets into the side seam of the pants to make them flow with the lines of the pants. I combined the pattern for pockets from Kershaw's instructions on how to make trousers with the pant draft I based on Chunman-Lo's pant draft.
Now that I had my pattern I began using a serger to sew my seams. Sergers are good for sewing and binding seam allowances at the same time so that you can avoid using a lining. They are quick and strong and can be seen in most commercially constructed clothing.
After serging my seams and seeing the shape of the overalls, I decided that I wanted to add hand made brass buttons for the shoulder straps to clip on to. I made them by using an iron worker (see Fig. 7) to punch holes in a piece of 1/8" brass plate. I then drilled holes in the centres of the punched out pieces and used hammers and heat to create a textured and aged surface (Fig.10).
When I had all of my buttons I began planning how they would be spaced. I used fusible interfacing on the underside of the front of the overalls to hold the fabric stiff to compensate for the weight of the heavy buttons, but as I began testing them, I realized that it needed an extra layer. I felt that it needed some leather to make it fit aesthetically with the mask.
