Frequently Asked Questions
- Is Black the bobbin even when the top thread isn't black?
- On a dark backing, yes — the bobbin matches the backing, not the top. Grey or navy top thread over a black back still runs Black in the bobbin so every stitch that shows on the reverse disappears.
- What completes the all-dark quilt system?
- Black backing + Hobbs Heirloom Black 80/20 batting + Black Magna-Glide bobbins — dark at every layer, so nothing light shadows, beards, or flecks through anywhere.
- Why does lint-free matter most in this jar?
- Cotton bobbin lint reads as white dust on black stitching — the filament poly's clean running is cosmetic as well as mechanical on dark work.
- Where does Black stop and Smoke start?
- Black under true black and near-black backs; a dark grey backing often blends better with a Smoke-family thread. Hold a strand against the backing — the one that vanishes wins.
- Same magnetic-core behavior?
- Identical — constant tension full-to-empty, which shows clearly on dark backings where tension flecks would telegraph.
