# **How to Choose 15 MODIFIED GREEN Polypropylene (Polypro) Yarn / Parachute Posts for Fly Tying**
Fly tying is both an art and a science, requiring precision in material selection to create effective and durable flies. Among the essential materials for parachute-style flies, **15 MODIFIED GREEN Polypropylene (Polypro) Yarn** stands out for its buoyancy, visibility, and ease of use. In this guide, we’ll explore how to choose the best poly yarn for your fly-tying needs, ensuring your flies perform flawlessly on the water.
## **Why Choose Polypropylene Yarn for Parachute Posts?**
Polypropylene yarn is a popular choice among fly tyers for several reasons:
1. **Superior Buoyancy** – Unlike natural fibers, poly yarn repels water, keeping your parachute posts floating high even after multiple casts.
2. **Bright Visibility** – The **MODIFIED GREEN** hue offers excellent contrast against the water, making it easier for anglers to track their flies in fast-moving currents.
3. **Durability** – Polypro resists fraying and maintains its structure, ensuring your flies last longer.
4. **Ease of Use** – The smooth texture allows for easy wrapping and securing on the hook shank.
## **Key Factors When Selecting Poly Yarn for Fly Tying**
### **1. Thickness (Denier & Strand Count)**
The **15 MODIFIED GREEN Polypro Yarn** refers to a specific thickness and color optimized for visibility and buoyancy. Thinner yarns (e.g., 12-15 denier) work well for small midge patterns, while thicker options (20+ denier) suit larger dry flies.
### **2. Color & Visibility**
While **MODIFIED GREEN** is highly visible in most conditions, some anglers prefer fluorescent orange or white for different lighting. Choose based on water clarity and light conditions.
### **3. Texture & Stiffness**
A slightly stiff yarn holds its shape better when wrapped, creating a more stable parachute post. However, overly stiff yarn can be harder to work with, so test different brands for the right balance.
### **4. Floatability & Water Repellency**
High-quality poly yarn should resist water absorption. If your yarn sinks after a few casts, consider treating it with a floatant or switching to a more hydrophobic brand.
### **5. Brand Reliability (KyleBooker Recommendation)**
Not all poly yarns are created equal. **KyleBooker’s 15 MODIFIED GREEN Polypro Yarn** is engineered specifically for fly tying, offering consistent thickness, vibrant color retention, and long-lasting buoyancy—making it a top choice for professional and amateur tyers alike.
## **How to Use Poly Yarn for Parachute Posts**
1. **Measure & Cut** – Trim a small section (about 1-2 inches) depending on fly size.
2. **Stack & Align** – Flatten the fibers for a clean post.
3. **Secure & Wrap** – Tie in at the hook bend, then spiral-wrap upward to form the post.
4. **Trim Excess** – Neatly trim any stray fibers for a clean finish.
## **Final Thoughts**
Choosing the right **15 MODIFIED GREEN Polypropylene Yarn** can make or break your parachute fly patterns. By focusing on thickness, color, texture, and brand quality (like **KyleBooker’s premium offering**), you’ll ensure your flies stay buoyant, visible, and effective on the water.
