Frequently Asked Questions
- Mercury or Cool Grey 3 — both cool medium greys?
- Job description: CG3 blends and disappears; Mercury holds presence and reflects. Invisible neutral work runs CG3; visible design-forward quilting runs Mercury. Same value zone, opposite intents.
- Where in the silver ladder?
- Between CG3 and Silver (10536) — more polish than the workhorse, less near-metallic flash than Silver. The middle rung of definition-with-restraint.
- What does it do on white grounds?
- Soft silver linework — the quilting reads as a gentle grey highlight, the signature look of modern minimalist quilts where stitching is the design.
- Feature-quilting use?
- Its specialty — feathers, geometrics, and custom motifs on grey or white grounds where the polished line should draw the eye.
- Bobbin pairing?
- CG3 or Light Grey Magna-Glide — nearest tonal jars that support without competing.
