Frequently Asked Questions
Blizzard or Snow — the So Fine! white decision?
Match the fabric's processing: on optically brightened modern cottons, Snow reads a hair cream and Blizzard disappears; on natural-white fabrics the reverse. Hold both against the fabric — one vanishes.
What is optical brightening in thread?
A treatment that reflects more visible light — the same chemistry modern white fabrics use, which is exactly why Blizzard matches them where untreated whites can't.
Why 50-weight for white-on-white?
The genre is pure texture — fine matte thread lets dense quilting read as sculpted relief without visible thread lines crossing the design.
Both positions?
Blizzard top and bobbin on white-on-white work — consistent brightness and balanced fine tension through the sandwich.
Batting to match?
Bleached only — a natural batting under an optically bright top and thread drags the whole sandwich warm; bleached keeps every layer in the same register.
