Gather plain paper, brewed coffee, a shallow tray, and paper towels
Brew a strong cup of coffee and let it cool
Place the paper on a flat surface
Lightly dip the paper into the coffee or brush coffee over it evenly
Let excess coffee drip off
Blot gently with paper towels if needed
Crumple the paper slightly for a worn look, then smooth it out
Leave the paper to air-dry completely
Repeat the coffee application for a darker stain if desired
Write the letter after drying, or write before soaking if you want faded ink effects
Let the finished letter dry fully before handling
