Frequently Asked Questions
- What does the 50-weight actually change versus 40wt greys?
- Thread presence — finer thread means smaller stitches and less bulk on the surface, so quilting reads as texture and shadow rather than visible line. It's the difference between drawing on the quilt and sculpting it.
- Silver Screen So Fine! or Silver/Mercury Glide?
- Opposite intents: the Glide silvers are lustrous and meant to be seen; Silver Screen is matte and meant to disappear. Statement quilting goes Glide, integration quilting goes So Fine!.
- Why does competition work specify fine thread?
- Judges score thread integration — how completely the stitching becomes part of the surface. 50-weight matte grey on grey fabric is close to the theoretical limit of that.
- Tension notes for the switch?
- Slightly lighter top tension than 40wt settings, tested on a strip — then So Fine! runs as reliably as anything in the studio.
- Bobbin pairing?
- So Fine! both positions for the finest result, or Light Grey / CG3 Magna-Glide jars for production convenience.
