For everyday production: Omni 40wt polyester on top, Bottom Line 60wt in the bobbin. This combination covers 90% of all longarm quilting perfectly.

Thread weight numbers are counterintuitive — higher number = finer thread. 40wt is thicker and more visible. 60wt (like Bottom Line) is ultra-fine and nearly invisible. Use 40wt on top, 60wt in the bobbin for balanced tension.

Most common causes: tension too tight, dull needle, thread snagging somewhere in the thread path, or the cone is unwinding incorrectly. Re-thread completely first. Then check needle condition. Then check tension.

Top tension is too tight, or bobbin tension is too loose. Loosen top tension slightly and re-test. If bobbin thread still shows, also check that the bobbin case is fully seated.

Yes — longarm machines work with any quality cone thread. Inferior budget threads produce more lint, inconsistent tension, and more breakage. Stick with quality brands: Superior, Fil-Tec, Aurifil.

A 6,000-yard Omni cone covers approximately 4–6 standard queen quilts at medium density. Dense custom quilting may use 2,000+ yards per quilt.

You can, but it’s not ideal. A warm cream or medium gray is the most versatile — it blends with the widest range of fabrics. For customer work, matching thread value to the dominant fabric produces the best results.

40wt works well. Some quilters prefer 50wt (King Tut or Aurifil) for very dense micro-stippling where they want the thread to sink slightly into the fabric rather than sit on top.

Not recommended — regular sewing thread (on small spools or bobbins) isn’t designed for the speed and tension of longarm machines. Use cone-format thread specifically designed for longarm or industrial machines.

No — this is a myth. Polyester thread on cotton quilts has been used by professional longarm quilters for decades without fabric damage. The concern is theoretical; in practice, well-made polyester thread causes no issues.

Hold both thread tails (top and bobbin) when you start the first stitch. After 3–4 stitches, you can release them. Starting without holding tails causes birds nests under the quilt.

For most quilting, a neutral bobbin (cream, light gray) that approximately matches the quilt backing is fine. Only color-match the bobbin closely when the backing is a dark solid where any contrast would be noticeable.

Don’t go from full stop to full speed suddenly. Accelerate gradually and decelerate gradually. Sudden speed changes stress the thread at the needle eye and cause breaks.

Trilobal polyester (like Glide) has a three-sided fiber cross-section rather than round. This creates a higher sheen by reflecting light from multiple angles — the signature Glide finish that makes quilting designs pop.

Yes — Aurifil 50wt works on most longarms. It comes in large cone format. Be aware it produces more lint than polyester, so clean your machine more frequently when using it.
