Step 3: Sewing the jacket
For complete instructions on how to assemble and sew a piece of clothing, I will recommend another tutorial on this site. This is on of my first sewing projects, and I have limited skills. I have assembled the jacket inside out. I have mostly used a jeans seam, with a strong polyester thread. This makes it a solid piece of clothing.
The original jacket, being a running-jacket, has a thin netting fabric underneath both arms to keeps your body cooler under sweaty conditions. I have replaced this with a comfortable thin wool fabric. When sewing this thin wool together with a thick hemp denim, make sure not to stretch the cloth. I was forced to undo the seams more than once, and I assure you, opening up a seam on thin wool is a bit of a task!
