Frequently Asked Questions
How does Pineapple differ from Daffodil?
Pineapple is the more saturated tropical yellow, Daffodil the fresher spring yellow with a cleaner cast. On vivid summer and citrus fabrics Pineapple blends better; on soft spring botanicals, Daffodil is the truer match.
Is Pineapple a good thread for children's quilts?
Yes — the fine matte finish keeps busy children's prints from getting shinier, and the polyester holds its vivid yellow through the heavy washing kids' quilts receive.
What bobbin pairs best with So Fine! 419 Pineapple?
A fine yellow polyester bobbin — Bottom Line in yellow, or a Bright Yellow pre-wound on yellow backings — hides cleanly at balanced tension across bright production.
