Superior Threads Bottom Line 60wt Polyester Thread 2743 m Cone — Dark Green, Low-Lint Bobbin & Quilting Thread

Superior Threads Bottom Line is a 2-ply, 60-weight 100% polyester thread on a generous 3,000-yard cone, designed to be a low-lint, near-invisible option for bobbins, quilting, applique, and machine sewing.

This long cone of Bottom Line in shade #643 Dark Green delivers a fine, smooth polyester filament that blends into seams and quilt backs while standing up to high-speed, longarm and domestic machines. Because it's lightweight and lint-resistant, it performs especially well as a bobbin thread or whenever you need a subtle finish—yet it still offers the strength and durability expected from polyester. The 2-ply construction balances softness with stability, giving reliable stitch formation without bulk.

How does this thread behave as a bobbin thread?

Bottom Line’s very fine 60-weight profile makes it an excellent choice for bobbins because it stays out of sight while supporting top stitches without adding thickness. Its low-lint construction reduces buildup in bobbin cases and tension assemblies.

• 2-ply, 60wt polyester keeps bobbin thread thin and even
• 3,000-yard cone limits bobbin changes during large projects
• Low-lint filament minimizes machine maintenance
• Strong polyester resists breakage at high stitching speeds

Will this thread work for quilting, applique and piecing?

Yes—its near-invisible drape and small diameter make it ideal for fine quilting, micro-stippling, piecing and machine applique where you want seams to disappear or not add bulk. The colour #643 Dark Green blends well on darker fabrics and can be used on top or bottom depending on your visual goal.

• Great for quilting techniques that require thin, unobtrusive thread
• Suitable for both piecing patchwork and machine applique edges
• Holds up in micro-stippling and dense quilting patterns
• Large cone size supports long sessions without rethreading

Is this thread compatible with my machine and what care does it need?

Bottom Line is compatible with most longarm, midarm and domestic sewing machines as a top or bobbin thread. Regularly cleaning lint and checking tension will optimize performance; use appropriate needles and thread paths to avoid shredding.

• Works with all standard longarm and domestic machines
• Use fine sewing/quilting needles for best results
• Clear proper thread path and routine cleaning reduce issues
• Polyester resists shrinking and handles laundering well

What makes the 3,000-yard cone a practical choice?

A 3,000-yard cone significantly reduces interruptions for reloading, especially on large quilts or production sewing. The cone size is cost-efficient for frequent sewers and professionals who prefer fewer thread changes and consistent colour across large runs.

• Spares time with fewer cone swaps during long projects
• Economical for frequent users and production work
• Consistent colour across the entire project without joins
• Convenient for winding multiple bobbins from one source

Who this is for: This 3,000-yard cone of Superior Threads Bottom Line in #643 Dark Green suits home quilters, longarm operators, sewing professionals and hobbyists who want a slim, durable polyester thread for bobbins, delicate quilting, piecing and applique. Choose this thread if you need a near-invisible, low-lint option that supports extended stitching sessions and holds up under fast, dense sewing.
