Frequently Asked Questions
Where does Bright Blue take over from Light Blue?
At royal saturation — team blues, cobalt solids, and patriotic vivid blues need 636's depth to disappear, while nursery and sky blues stay with 610. The two-spool pair covers the blue family.
What tops pair with Bright Blue in the bobbin?
Out of the Blue, Polo, and Great Falls So Fine! tops, or vivid blue Glide — the fine bobbin keeps team and patriotic quilt backs flawless at balanced tension.
Is Bright Blue good for T-shirt quilt bobbins?
Yes — team-blue backings are standard on sports T-shirt quilts, and the strong fine 60wt handles the mixed knit-and-interfacing sandwich without adding bulk at seam crossings.
