Frequently Asked Questions
- Why is White the jar studios reorder most?
- Light backings dominate the queue, and white tops use more thread than every other color combined — the bobbin consumption follows. Running out of white bobbins mid-quilt is the classic avoidable studio interruption.
- White jar or a grey neutral?
- By backing: bright white and near-white backs need true White — even CG3's slight grey shows there. Everything a shade darker, the grey jar covers.
- Why does the magnetic core matter most on white work?
- White-on-white quilting shows tension flaws mercilessly — constant magnetic tension keeps stitch quality identical from a full bobbin to an empty one across a surface where every variance reads.
- Matched with White Glide on top?
- Exact color match — the standard pairing for white quilts, one continuous white through the sandwich.
- Warm-white backings?
- Step to Cream (20001) or Linen (10WG1) jars — bright white bobbin against cream backing reads cool at the stitch line.
