Jeremy Williamson He gave me some good pointers: 1. He uses green needle and not yellow needle, because its safer. 2. He scratches the tip of the needle off to blunt it, so he can use it as a spoon 1. fuck this is smart, I didn’t do that at all and was sitting there picking away at the needle 3. uses syringe and not cotton tip because you get better grip
