Thank you so much, this is exactly the advice I needed! I'll try it as you said, and see how it turns out! The funny thing is, 10 oz. Vegetable tanned leather was exactly what I was going to get, so I'll just go along with that plan, and get the patterns you suggest! My thanks to you mate, and finally:

Good afternoon all, I'm an utter novice at leather work, but I have a project in mind that I need some advice on. I have been browsing around the forums for some time now, and I have a rough Idea of what I want to do, but no clue how to go about it! I'm attempting to make a piece of realistic-looking armor to look sort of like a prosthetic arm for a Steampunk costume I'm working on, and I was thinking of molding the leather to my specific shape so I could have good forearm/ elbow/ upper arm and shoulder joints that I knew would fit, but I need some advice on molding, sizing, and in general what kind of leather and material I should use. I was thinking around 10 oz. Veg Tan leather, with a wet mold process using my own arm to shape it then an oven bake technique I was seeing discussed on here, and I was wondering if anyone had some tips on what kind of tools or techniques would be best for a beginner to use for a project such as this? Any help would be very much appreciated!
