How to Tie a Blood Knot?

The blood knot is most appropriate for joining two pieces of monofilament, or fishing line, that are roughly the same diameter. It is also used for making fly leaders. With practice, you can quickly catch on to this helpful knot. First, wrap one of the lines around the other three of four times, then loop the end back through the spot created between the two lines. Repeat with the other line, passing the end of the line through the same spot, but in the opposite direction. Gently pull on the standing ends to tighten, and trim the ends.
