Step one:
Make the basic shape of the splatters or dripping blood you'd like
Step two:
Take a red colored pencil and make the lines a little les defined for a more realistic look
Step three:
Add some different shades of red colored pencil to add depth
Step four:
Add in some black, but press lightly
And that's it!
Sorry, it usually looks better ON something......
But that's how I do it at least :p
