## **Why Choose Semperfli Classic 70D 12/0 Waxed Thread?**
Semperfli’s **Classic 70D 12/0 Waxed Thread** is designed for precision and durability. Here’s why it’s a favorite among fly tyers:

– The **12/0 size** is ideal for small to medium-sized flies, ensuring smooth tying without overpowering delicate patterns.
2. **Waxed for Better Control**
– The thread is lightly waxed, providing better grip and preventing unraveling while tying.
– The wax coating also helps in securing materials like dubbing and feathers more effectively.
3. **Wide Color Selection**
– Available in **over 30 colors**, including natural and vibrant shades, making it easy to match any fly pattern.
– The thread’s color consistency ensures uniformity in your flies.

## **How to Choose the Right Thread for Your Needs**
When selecting **Semperfli Classic 70D 12/0 Waxed Thread**, consider the following factors:
### **1. Fly Size & Application**
– **Small flies (midges, nymphs):** The **12/0 size** is perfect for delicate patterns where bulk must be minimized.
– **Medium-sized flies (dry flies, emergers):** The thread provides enough strength without adding unnecessary weight.
– **Larger flies (streamers, saltwater patterns):** While 12/0 works, you may want a thicker thread (like **140D or 210D**) for added durability.
### **2. Color Matching**
– **Natural tones (olive, brown, black):** Essential for imitating insects and blending with natural materials.
– **Bright colors (red, orange, fluorescent):** Great for attractor patterns and adding contrast.
### **3. Waxed vs. Unwaxed Thread**
– **Waxed thread (like Semperfli Classic 70D 12/0):** Better for securing materials and preventing slippage.
– **Unwaxed thread:** Offers a smoother finish but may require more wraps for security.
### **4. Strength & Durability Needs**
– If you frequently tie **small, delicate flies**, this thread’s strength-to-thickness ratio is ideal.
– For **heavier patterns**, consider pairing it with a stronger underbody thread or opting for a thicker variant.
