Frequently Asked Questions
Why is CG3 the studio's default bobbin?
Grey neutralizes — against light, medium, and many multicolor backings a mid cool grey blends where white flashes and dark contrasts. One jar covers the widest share of the queue.
Can it run under white or cream top thread?
Yes — that's its signature move: many studios run CG3 in the bobbin regardless of top color whenever the backing is light-to-medium, because any pull-through reads as shadow rather than contrast.
Where does it stop working?
Bright white and very dark backings — white backs want the White jar, dark backs want Black. CG3 owns everything between.
Matched top-and-bobbin work?
The jar matches the 10CG3 king spool exactly — for grey quilts, matched CG3 top and bobbin gives one continuous color through the sandwich.
What keeps tension consistent jar after jar?
Industrial pre-winding plus the magnetic core — tension at the last stitch of the last bobbin equals the first, which is the whole Magna-Glide proposition.
