602 Gold Bottom Line Polyester Thread

602 Gold Bottom Line Polyester Thread from Superior Threads is warm gold at 60 weight — the ultra-fine tier below So Fine!, born as a bobbin thread and equally potent as the most invisible gold top thread available.

Frequently Asked Questions

Where does Bottom Line sit in the weight ladder?

The bottom — Glide/Omni 40wt (visible line) → So Fine! 50wt (fine texture) → Bottom Line 60wt (nearly gone). Each step halves the thread's visual presence; 60wt is the last stop before monofilament.

The bobbin logic it's named for?

Fine top threads want fine bobbin partners — a 40wt bobbin under a 50wt top pulls and bulks; Bottom Line underneath keeps the back as refined as the front and packs more yards per bobbin wind.

When does gold need to be this fine?

Dense quilting on gold fabrics — micro-fills and background stipple in a matching gold that must not build thread ridges; and binding/appliqué stitching on golds where the thread should disappear entirely.

Tension reality at 60wt?

The biggest adjustment in the Superior lineup short of MonoPoly — lighter top tension, fine needle, and a proper test strip; set once, it runs clean.

Its Military Gold relationship?

The fine sibling — Military Gold Glide draws the visible ceremonial gold line; 602 Bottom Line is the same warmth when the gold should whisper.
