Originally posted by DHR: you can use an old shirt that fits you well. It's best to cut it apart and trace the pices onto paper. you can then customize however you want by adding a hood, armpit gussets etc. It's also not a bad idea to use the pattern you've created to make a shirt out of an old sheet or something to make sure everything fits right before cutting into that buckskin. Are you using braintan? If so i can offer a few more tips if you're intersted. good luck Dan
