Tinsel in Fly Dressing: Mylar vs. Metal for Flash and Realism

In fly dressing, tinsel is typically made of Mylar, a plastic, or metal like aluminum or brass, and can be flat, oval, or holographic. 

Here’s a more detailed explanation:

• Mylar Tinsel:
• Mylar is a common type of plastic used for tinsel, offering a variety of colors and finishes, including holographic. 
• It’s often used for ribbing, adding flash, and creating wing cases. 
• Mylar tinsel comes in different widths and can be cut from larger sheets or purchased in spools. 
• Metal Tinsel:
• Metal tinsel, often made of aluminum or brass, is another option for fly dressing. 
• Metal tinsels can be flat, oval, or French oval. 
• Metal tinsels are known for their durability and are often used for patterns that need to withstand toothy fish. 
• Other Materials:
• Some fly tyers also use other materials like chenille, which is typically made from synthetic fibers like polypropylene and rayon. 
• Micro tinsel is a fine, multi-stranded thread that can be used for ribbing and adding flash. 

Fly dressing tinsel sizes are often correlated to hook sizes, with common examples including 16/18, 14, and 12, and are available on spools like thread. 

Here’s a more detailed breakdown:

• Correlation to Hook Size:

Tinsel sizes are often roughly coordinated to the size of the fly you are dressing, with examples like 16/18, 14, and 12. 

• Presentation:

Tinsel comes on a bobbin just like fly dressing thread, from many of the same brands. 

• Other Sizes:

While the correlation to hook size is common, you may also find tinsels labeled as x-small, small, medium, and large. 

• Purpose:

Tinsel and flash are synthetic materials used to create shiny and reflective elements that imitate the appearance of fish scales and other natural prey.
