I started by covering my nail in a light neutral colour simply because I though it would look nicer but this is a step you can easily skip. I also added a messy black tip as I like that it intensifies the colour right at the tip meaning it looks like that part has more blood.
After that was dry I mixed two colours together a dark brown and a burgundy shade to achieve the colour I wanted. I then used a really old lip brush, but you can use what every you have to paint on the tips and then going for the middle to the tip I added some blood like drips. I don’t think this has to be neat at all, if anything the messiness adds to the final result.
What are you doing for Halloween?
