Half Blood

The simplest, and most commonly used knot for attaching flies is the simple Half Blood. This knot should be used with caution, because under some circumstances it is inclined to slip.

 
 

Step 1.

This knot is tied by passing the line through the eye of the hook, wrapping the tag arround the main line three to six times, then passing the tag back through the first loop made around the eye of the hook. The finer the diameter of the line in relation to the diameter of the hook eye, the greater the number of turns (up to six), that should be made.
