The Beadsmith Fireline Micro-Fused Braided Bead Thread 3.63 kg, 114 m Smoke Grey — .007in Thin, Low-Stretch

The Beadsmith Fireline by Berkley is a micro-fused braided bead thread made from ultra-strong Dyneema, delivering a thin, low-stretch 8 lb line ideal for bead weaving, stringing, and heavy-finish jewellery work.

Engineered from gel-spun polyethylene (Dyneema), Fireline combines exceptional tensile strength with a slim 0.007" (.17 mm) diameter, giving you a discreet yet resilient cord for intricate jewellery projects. Manufactured in the USA and supplied in a 125-yard spool in smoke grey, this braided thread was adapted from fishing line technology to meet the needs of beaders who require durability without bulk. It resists stretching and tangling, accepts needle threading, and performs well with heavier beads and metal findings.

How does Fireline perform for bead weaving and stringing?

Fireline’s braided micro-fused construction provides a stable, low-stretch platform that holds bead patterns and knots securely. Its thin diameter lets it pass through small bead holes multiple times, while the high tensile strength helps prevent breakage under tension.

• Thin 0.007" (.17 mm) cord for multiple passes through seed beads
• 8 lb test rating for confidence with heavier components
• Minimal stretch preserves stitch tension and shape
• Smoke grey colour blends with many bead palettes

What are the best ways to cut and finish Fireline?

Because Fireline is exceptionally strong and resists fraying, sharp scissors are recommended for clean cuts, but heat sealing yields the neatest results. A handheld thread burner offers precise sealing without bulky knots; if you use scissors, consider a small dab of glue on knots for extra security.

• Use sharp, precise scissors for straight cuts
• Seal ends with a thread burner or brief flame to prevent frays
• Small drop of jewellery glue can secure finished knots
• Trim sealed ends carefully to avoid melting nearby beads

Will Fireline work with my needles and beads?

Fireline is needle-compatible and slides through many bead holes despite its strength, making it suitable for both beading needles and regular sewing needles sized for fine cord. Check bead hole diameters before multi-pass techniques, and choose needle eye size accordingly to ensure smooth threading.

• Threads through beading needles and many small bead holes
• Suitable for woven techniques requiring multiple passes
• Works with glass, metal, and many natural beads when hole size permits
• Non-elastic behavior keeps woven patterns stable

How durable is Fireline for wearable jewellery?

Originally developed for fishing, the Dyneema fibre offers industry-leading strength per diameter, so finished pieces resist daily wear and tear better than many classic beading threads. The braided, micro-fused finish also reduces internal abrasion, helping clasps and findings last longer under repeated movement.

• Gel-spun polyethylene fibre provides very high tensile strength
• Low abrasion and limited stretch improve longevity of wearables
• Works well with metal findings and heavier beads without snapping
• 125 yards per spool supports multiple projects or larger pieces

Who is this for? Fireline by The Beadsmith is made for bead artists and jewellery makers who need a slim, robust thread that holds tension, withstands heavy components, and passes through small holes. It’s a go-to choice for advanced bead weaving, bead embroidery, and makers who prefer a heat-sealable finish. If you favor stable stitches, minimal stretch, and a neutral smoke-grey tone that complements many colorways, this micro-fused braided thread will fit cleanly into your toolkit.
