Spread a thin, even layer of adhesive onto your paper or fabric. This is the only part where patience matters. If you glob it like peanut butter, your grit will sink into a mushy mess. If you spread it too thin, the nails will fall off and your paper will weep lonely grit tears.
Now, here’s the fun part: sprinkle your crushed nails or grit onto the glue like you’re seasoning a steak for a giant robot. Don’t be shy—cover every spot. Then, press it down firmly with a rolling pin or a heavy book you hate (I recommend a copy of “War and Peace”). Let it dry for 24 hours, and voilà—you have made nails paper.
