Frequently Asked Questions
- The So Fine! neutral run, extended?
- Blizzard → Snow → Pearl → Bone — optical white to golden ivory, the fine-weight mirror of the warm Glide ladder. Bone owns the fabrics with genuine golden cast where Pearl still reads a half-step neutral.
- Bone So Fine! or Bone Glide — the pair?
- The standing weight/finish split at the same color — Glide Bone at 40wt luster for quilting that reads warm and catches light; this at 50wt matte for quilting that dissolves into muslin. Feature versus integration on the same fabric family.
- Why is muslin its home ground?
- Unbleached muslin is exactly this golden-natural tone — fine matte Bone on muslin backs and tops reads as pure texture, the reproduction-quilt finish at competition weight.
- Its Aurifil neighbor?
- 2021 Natural White covers the same register in cotton — fiber philosophy picks between them; the tone is shared.
- Setup?
- So Fine! standard — light fine-weight tension, #16 needle, strip test.
