Frequently Asked Questions
Is Washed Denim the right thread for actual denim quilts?
Yes — on jeans-recycled and denim-look quilts its faded medium blue blends across wash variations, and the strong fine polyester handles the heavier seam crossings of denim work better than cotton at the same weight.
How does Washed Denim differ from Out of the Blue?
Out of the Blue is vivid and saturated; Washed Denim is deliberately faded and greyed — worn indigo rather than fresh royal. On bright blues Out of the Blue blends better; on chambray, faded denim, and farmhouse blues, Washed Denim is the truer match.
What bobbin pairs best with So Fine! 509 Washed Denim?
A fine medium blue polyester bobbin — Bottom Line in denim blue, or a Cadet-toned pre-wound on blue backings — hides cleanly at balanced tension across casual production.
