413 Scarlet — The Classic Production Red
So Fine! 413 Scarlet is the clean, classic bright red — the production red standard in the So Fine! line. Named for the pure, vivid red of scarlet dye, it is the thread for the full range of red fabric production: Christmas quilts, patriotic quilts, traditional red-and-white designs, and any application where red should be vivid, clean, and reliably red. Its spiced neighbour is 412 Hot Chilies, with 414 Claret anchoring the deep wine end of the red run.

Frequently Asked Questions
Is Scarlet the right red for red-and-white quilts?
Yes — traditional red-and-white designs rely on a clean, true red, and Scarlet's pure position with the matte So Fine! finish keeps the classic look crisp without the sparkle a trilobal red would add.
How does So Fine! Scarlet compare to Glide Cardinal?
Both are clean production reds; the difference is finish and weight. Scarlet is #50 matte for blending texture, Cardinal is 40wt trilobal with sheen for visible presence. Many studios stock both and choose per quilt.
What bobbin pairs best with So Fine! 413 Scarlet?
A fine red polyester bobbin — Bottom Line in red, or a Cardinal pre-wound on red backings — keeps the back clean at balanced tension across holiday and patriotic production.
