Bottom Line 60wt Cone — White and Cream Shades
Choosing the right white or neutral Bottom Line is critical for invisible bobbin results on light fabrics. The full line is covered in the Bottom Line 60wt cone guide, with the grey-through-black range in the neutral and dark shades guide. The seven white-to-cream shades cover every variation:
- 624 Natural White — the most-used neutral; warm natural white for natural and warm-toned backs
- 621 Lace White — bright clean white for white-background quilt backs
- 655 Off White — slightly warmer than Lace White; for off-white and ecru backs
- 620 Cream — warm cream for cream and warm ivory backs
- 651 Ivory — warm ivory for ivory and aged-white backs
- 650 Champagne — golden-warm for champagne and warm-toned backs
- 654 Oatmeal — warm oatmeal for natural and unbleached back fabrics
Frequently Asked Questions
Why seven near-white bobbin shades?
Because most quilt backings are light, and at bobbin-matching distance the only thing that shows is a wrong undertone — a bright white bobbin flecking through an oatmeal muslin back reads as lint. Seven closely stepped whites mean one always sits inside the backing's own range.
Which white does a studio use most?
624 Natural White by a wide margin — warm natural white matches unbleached muslins, warm wide-backs, and most cream prints, which together dominate backing fabric sales. Studios typically keep multiple 624 cones and one each of the others.
How do I pick between Lace White, Off White, and Natural White?
Hold the cone on the backing in daylight: optic-white backs take 621, ecru-tinted whites take 655, and anything warmer takes 624. If two look equal, take the warmer — warm whites hide better in shadow than cool ones.
