The bottle is very very economical, so do not worry that the blood might not be enough. One does not need much, but it's tough can be easily diluted with water. I have applied undiluted on the face (Zombie) and in nose, ears and wounds applied it with a cotton swab. Then diluted to a saucer, toothbrush reingetunkt and sprayed onto the T-shirt .... good thing! It can be easily washed out again, white T-shirt is white again.
And ... I got something previously done than ever before. Child's play!
