## **How to Choose the Right Fly Tying Floss**
When selecting Uni Fly Tying Floss (or any floss), consider the following factors:

### **2. Material (Rayon vs. Nylon vs. Polyester)**
– **Rayon (Uni’s Choice)** – Smooth, glossy, and easy to work with.
– **Nylon** – Slightly more stretch but can fray.
– **Polyester** – Durable but lacks the sheen of rayon.
### **3. Color & UV Resistance**
