Every time I go to a Ren Faire I seem to come away with something that I need to make. After one trip I decided that I needed a leather pauldron. I would have loved to buy one of the gorgeous pieces there, but I just couldn't afford to and fortunately it ended up being a whole lot cheaper to make one. I checked out a couple there to see how they were constructed and went home to try and duplicate it myself.
Note: I didn't do a very good job of documenting this process with pictures. A lot of the pictures will simply be detail shots of the completed project. I hope this is still useful to you. I figured if I can't show the step in progress I can at least show what I'm talking about.
Step 1: Planning
There are a lot of different ways that you can make a pauldron. Different materials, different styles, etc. I definitely wanted it to be leather. I also decided to make it fairly simple. Just three segments and the straps. I liked the idea of being able to wear it on either shoulder so I decided it should have two buckles on the strap so whichever way I wore it I could still reach the buckle. I also decided that since I had never done any leather stamping I should keep any detail work simple.
I took some measurements of my arm and shoulder widths, made a simple paper mock-up, and then used it as a pattern to transfer it to the leather. In total there are eight pieces. Three segments for the body of the pauldron. Three straps for the buckle across your chest. Two straps for the buckle that fastens it to your arm.
For the straps that go to the center of the chest and back I measured from the corner of where the pauldron would sit to the center of my chest. For the strap that would connect those two I measured from the center of my chest, around my side to the center of my back. For the arm strap lengths I just figured about half the diameter of my arm. Then I added some length since they would all need to be attached and buckled together.
