Hiya allaya! We were asked to make a pair of prop 'vintage' shin guards for a documentary on the history of baseball. In the doc you won't actually see the props we made - they'll be filtered through post vfx grainy textures and stuff - and so we could have gone a little simpler, but we wanted to play with some scrap leather we had and ended up with the piece you see pictured. I've also included the photo collage that our client sent us to use as a reference.
Step 1: Retrofitting Existing Shin Guards
Our first step was to take an old pair of modern shin guards and modify them so that they began to assume the shape of the vintage ones. This meant cutting off the hard plastic shell and cutting away some of the extra padding along the top of the knees.
