How do you dye large pieces of leather?

To dye large pieces of leather, start by cleaning the leather thoroughly to remove any dirt or oils. Use a leather dye specifically formulated for large surfaces, applying it evenly with a sponge or brush in long, consistent strokes. Allow the dye to penetrate for the recommended time, then wipe off any excess. Finally, let the leather dry completely before applying a protective finish to enhance the color and durability.
