How do you tie a fly thread?

To tie fly tying thread to a hook, you wrap the thread over the hook shank multiple times and then lock it in place.

Here's a breakdown of the process:

1. Start wrapping: Wrap the thread over the shank of the hook, usually towards the back of the hook (near the barb).
2. Secure the thread: Make several wraps (3-5) to build a solid base.
3. Lock the thread: Cross back over the initial wraps with your thread. This secures the thread and prevents it from unraveling.
4. Trim the tag end: Cut off the excess thread (the "tag end") close to the wraps.

This method securely attaches the thread to the hook, providing a foundation for building the fly.
