Micro Fritz Gel Core by Semperfli – Tiny Fly Bodies and Micro Nymph Patterns

Overview

Semperfli Micro Fritz Gel Core is a chenille style core designed for ultra‑small fly work. It excels at shaping compact bodies and micro thorax segments on pattern sizes 16 through 20. With a precise 0.8 mm thickness, it delivers a slender, neat wrap that stays true under pressure during tying.

The gel core is engineered to keep fibers cohesive as you work, reducing stray strands and helping your wraps stay aligned from the first turn to the final touch. This is especially useful when building delicate nymph bodies where a clean silhouette matters as much as color and texture.

Each spool provides 6.5 yards (6 meters) of fritz, giving you plenty of material for multiple pattern variants without frequent re-spooling. A broad color lineup lets you match natural tones or experiment with subtle color layering to create lifelike bodies. Whether you are chasing mayflies, midges, or micro nymphs, this fritz offers a dependable base for tiny fly patterns.

What it is well suited for

• Small fly bodies and micro thoraxes on patterns sized 16–20
• Compact wraps that maintain a clean profile on delicate hooks
• Layering colors to achieve natural shading and segmented looks
• Tying nymphs and subtle micro patterns where fiber integrity matters
