Need help on designing a cape, shirt, pants, & eagle emb

[P. Clodius Secundus]

To darken a scratch-built hamata (usually 16 Ga. galvanized wire), soak the finished piece in white vinegar. That removes the coating. make sure you do this outside, it gives off gasses. Mostly hydrogen, I think. Rinse it with water and let it rust up then tumble it in bucket with some stones to knock off the surface rust. Then you can oil it or spray it with an acid solution used in autobdy work to stop rust. That will turn the rust into a hard gray/black patina. Make sure to have a subarmalis to wear under it when it is done or you'lltrash your tunic every time you wear it.
