The Sedimentary Rock Grey-Blue
Glide 14332 Shale is the cool, dark grey-blue of shale rock — a naturally structured, cool dark colour with the specific layered quality of sedimentary stone. For geological-inspired, industrial, and modern dark neutral quilts where grey-blue should feel as naturally grounded as ancient rock formations. It sits between the industrial Glide 25663 Gun Metal and the coastal Glide 10362 Harbor Grey, with Glide 10735 Stargazer carrying the same grey-blue depth into atmospheric territory.

Frequently Asked Questions
How does Shale differ from Gun Metal?
Gun Metal is a pure dark industrial grey, while Shale carries a clear blue influence — stone rather than machined metal. On charcoal and precision-grey fabrics Gun Metal blends better; on slate-blue, denim-adjacent darks, and stone-toned fabrics, Shale is the truer match.
Is Shale a good thread for men's and masculine quilts?
Yes — dark grey-blues are the backbone of masculine quilt palettes, and Shale blends across denim, chambray-dark, and slate fabrics while adding structured texture. It's a frequent single-thread choice for edge-to-edge work on dark modern tops.
What bobbin thread pairs best with Shale?
The matching Magna-Glide Delights bobbin in Shale is the standard pairing. Under dark grey or navy backings, a Gun Metal or Navy bobbin also hides cleanly across dark production runs.
