Step 1: You will need:
2: Safety pins of various sizes. (For this jackets I used size 0, 1, 2, and 3 steel and brass pins.)
3: A light colored pencil or chalk
4: A needle and thread
5: Optional: a dressmaker's dummy. This is very useful because it lets you see the overall effect of the image as you work. I like being able to constantly see what the worn jacket looks like, but working this way is harder on your arms. You also need to be careful not to pin th jacket to the dummy, as many of them are fabric-covered.
