KIVISIN 0.8mm Heavy-Duty Waxed Polyester Thread Kit — 12 Neutral Colours, 35yd Spools & 7 Needles for Leather & Bookbinding

KIVISIN 0.8mm heavy-duty waxed polyester thread is a strong, colourfast round thread kit designed for hand and machine leather sewing, bookbinding, and durable craft projects.

This kit includes twelve neutral shades of 0.8mm waxed polyester thread, each wound on kraft-paper spools and ready for upholstery, leatherwork, book repair, and outdoor crafts. The thread is made from high-tenacity 1260D/3 polyester microfibers twisted into a round cord, internally waxed for controlled tack and long-term durability. Also included are seven hand-sewing needles in assorted sizes so you can begin stitching right away. The combination of wax, fibre structure, and sizing makes this thread suitable for both precise hand stitching and robust machine applications, while the colourfast dyeing resists fading over time.

How durable is this 0.8mm waxed polyester thread for heavy-use leather items?

The thread is engineered for strength and longevity, made from three twisted 1260D polyester strands with microfibers that resist breaking under tension. Its inelastic, bonded structure helps seams hold shape under stress and the wax adds abrasion resistance and slight tack for neat stitches.

• Three-strand 1260D/3 polyester for high tensile strength
• Bonded and inelastic to prevent stretching and loosening
• Internally waxed to reduce surface buildup and increase abrasion resistance
• Can be fused cleanly by melting ends for secure finishes

What colours, lengths, and tools come in the kit?

The set supplies twelve neutral and practical colours on eco-style kraft-paper spools, sized for common leather and bookbinding needs. Each spool contains 35 yards (32 meters) of thread and the kit includes seven assorted hand-sewing needles to cover different stitch sizes and leather thicknesses.

• 12 neutral colours: black, beige, grey, dark grey, khaki, brown, dark brown, coffee, light coffee, army green, dark green, royal blue
• 35 yards (32 meters) per kraft-paper spool
• Seven assorted hand-sewing needles included
• Compact box storage for organized craft stations

How easy is this waxed thread to work with for hand sewing and machines?

The round profile and internal waxing make threading, pulling, and knotting smoother than many flat waxed alternatives. It’s suited for hand saddle stitching and compatible with many sewing machines used for heavy materials, though machine setups vary—test tension and needle size before committing to a full seam.

• Round waxed profile glides through holes and leather consistently
• Internal wax prevents sticky surface buildup yet offers slight tack for neat stitches
• Works for hand saddle stitch, bookbinding, upholstery, and many machine tasks
• Wax can be softened or reduced by washing with hot water and detergent if needed

Which projects benefit most from this thread kit?

This thread is made for any craft or repair that demands longevity and a clean finish. From bespoke leather goods to outdoor gear and book spines, the kit serves both beginners and experienced makers who need a reliable, all-purpose waxed thread.

• Handmade wallets, belts, bags, shoes, and saddlery
• Upholstery, furniture repairs, and heavy canvas stitching
• Bookbinding, journal repair, and craft macramé projects
• Jewellery, beading, and decorative braiding or wrapping tasks

Who is this for: Crafters, leatherworkers, bookbinders, upholsterers, and makers who need a sturdy, colourfast waxed thread that balances strength and workability. It’s ideal for anyone creating or repairing items that face regular wear — from small hand-sewn projects to heavy-duty seams — and for buyers who prefer eco-conscious spool packaging and a ready-to-use needle assortment.
