Frequently Asked Questions
- When should I use light grey bobbins?
- Use light grey bobbins when quilting with grey, blue-grey, or cool-toned medium neutral backing fabrics where white bobbins would read slightly bright and cream bobbins slightly warm. Grey bobbins provide the most neutral tonal match across cool and mixed-tone backing fabrics.
- Do I need grey bobbins or will white work?
- On many grey backings, white bobbins are acceptable if the bobbin stitching won’t be closely inspected. For heirloom quilts, customer quilts where the back is prominently displayed, or tonal wholecloth designs, matching bobbin color significantly improves the finished quality.
- Are these compatible with all M-style longarm machines?
- Yes — Magna-Glide Classic M-size bobbins are compatible with all longarm machines using M-style bobbins.
- What top threads pair best with light grey bobbins?
- Light grey bobbins pair naturally with Glide Cool Grey 3 (10CG3), Warm Grey 4 (10WG4), Silver (10536), and any light-to-medium grey or cool neutral top thread. They also work acceptably under most blue, purple, and cool-toned top threads.
- How does the case quantity compare to individual jars?
- The case provides better per-bobbin economy and extended production inventory versus purchasing individual jars.
