Frequently Asked Questions
- When does Genoa Gray beat the lighter So Fine! grays?
- On medium-dark to dark backgrounds — charcoal, deep gray, dark navy — where a light or medium gray washes out. Genoa Gray keeps definition without jumping to black.
- What does it do on black?
- A deliberate dark-gray contrast rather than maximum-contrast black-on-black — a more nuanced effect popular in modern high-contrast quilts.
- Genoa Gray So Fine! or Smoke Glide?
- Smoke Glide is 40wt with luster — shimmering, visible definition on dark fabric. Genoa Gray is 50wt matte — finer, texture-only stitching that sinks into the surface. Seen versus felt.
- Why do competition quilters use it on dark tops?
- Judges read fine-weight stitching on dark fabric as texture and craftsmanship rather than visible thread color — the elite-work signature. Genoa Gray delivers that on the dark half of the palette.
- How does it handle dark scrappy mixes?
- It harmonizes across navies, charcoals, dark teals, and burgundies without the starkness of pure black — one thread across the whole dark scrappy surface.
