# **How to Choose Fly Tying Thread: 2 Spools of Uni Trico Thread, 17/0 Very Fine for Small Flies**

When it comes to fly tying, the thread you choose can make or break your fly. Whether you’re crafting delicate midges, tiny nymphs, or intricate dry flies, the right thread ensures durability, precision, and a professional finish. Among the many options available, **Uni Trico Thread in 17/0 (very fine)** stands out as a top choice for small flies. In this guide, we’ll explore why this thread is a must-have for fly tyers and how to select the best tying thread for your needs.

## **Why Thread Selection Matters in Fly Tying**

Fly tying thread serves multiple purposes:
– **Securing materials** – It binds feathers, fur, and synthetics to the hook.
– **Building structure** – It helps create smooth underbodies for flies.
– **Adding durability** – A strong thread prevents flies from unraveling.

For small flies, a **very fine thread** like **Uni Trico 17/0** is essential because:
✔ **Minimal bulk** – Thick threads can overpower tiny hooks.
✔ **Smooth wraps** – Fine threads allow for tight, clean wraps.
✔ **Better aesthetics** – Thin thread blends seamlessly into small patterns.

## **How to Choose the Right Fly Tying Thread**

When selecting thread for small flies, consider these factors:
