Superior Threads Bottom Line 60wt 2-Ply Polyester Bobbin Thread — 2743 m Cone Ivory, Lint-Free Smooth Stitching

Superior Threads Bottom Line 60-weight is a 2-ply, 100% polyester embroidery and quilting thread sold on a 3,000-yard cone in Ivory for smooth, near-invisible stitching and ideal bobbin use.

Lightweight and lint-free, this Bottom Line thread from Superior Threads delivers a fine, strong filament suited to machine quilting, applique, embroidery, and piecing. Its 60-weight profile and two-ply polyester construction make it durable enough for frequent stitching while remaining thin enough to disappear into seams or serve as an unobtrusive bobbin thread. The long 3,000-yard cone reduces changeovers during long projects and is compatible with home and longarm machines.

How does this thread perform on the bobbin in machine quilting?

Bottom Line is commonly used as a bobbin thread because its thin 60wt diameter lays smoothly without bulk, reducing thread build-up and tension problems. The polyester fibre resists breakage and the near-invisible ivory colour blends with many top threads.

• 60-weight fine profile prevents raised seams and puckering
• 2-ply polyester adds strength for fast stitch speeds
• 3,000 yards per cone minimizes bobbin changes
• Works on both domestic and longarm machine bobbin systems

Will this thread work for applique, piecing, and micro-stippling?

Yes — the fine, low-lint nature of Bottom Line makes it a go-to for detailed work where subtle stitching is preferred. It blends into fabrics and allows decorative top threads to stand out while maintaining consistent stitch formation for dense stitching techniques.

• Near-invisible finish ideal for applique edges and bindings
• Lightweight for dense quilting and micro-stippling without bulk
• Smooth feed and low lint help reduce machine cleaning needs
• Compatible with hand techniques like English Paper Piecing

Is this thread durable enough for everyday sewing and longarm use?

Although very fine, Bottom Line is spun as a two-ply polyester, which gives it surprising tensile strength for everyday and high-speed longarm stitching. Polyester also resists moisture and abrasion better than many natural fibres, improving longevity of sewn seams.

• 2-ply construction increases break resistance during high-speed stitching
• Polyester fibre retains strength and resists moisture
• Suitable for continuous longarm quilting sessions thanks to large cone size
• Recommended for both piecing and dense quilting patterns

What practical details should I know before buying the 3,000-yard cone?

The cone contains 3,000 yards of 60-weight thread in Ivory (#651), sized to fit most cone holders and thread stands. Thread tension should be tested and adjusted based on machine and project; because the thread is fine, spool orientation and a steady feeder help prevent breakage or slips.

• Colour: Ivory (#651), versatile for light to medium fabrics
• Length: 3,000 yards reduces interruptions for large projects
• Recommended for cone stands or machines with cone adapters
• Test tension on scrap fabric before stitching a final project

Who is this for? Crafters, quilters, longarm operators, and machine embroiderers who want a reliable, fine polyester thread that disappears into seams or performs as a low-profile bobbin thread will appreciate this product. If you work on large quilts, do a lot of micro-stippling, or need a neutral ivory bobbin thread with good strength and very low lint, the Superior Threads Bottom Line 60-weight 2-ply 3,000-yard cone is designed to make those tasks easier and more efficient.
