Frequently Asked Questions
- Why match the bobbin color to the top thread?
- For tonal quilting where both sides of the quilt will be visible, matching bobbin and top thread provides a consistent appearance on both the quilt face and back. It also prevents any color show-through at quilt edges where the bobbin thread might be visible.
- Can I use a white or cream bobbin with Cool Grey 3 top thread instead?
- On most quilts where the back won’t be closely examined, a white or cream bobbin works acceptably under a grey top thread. The Cool Grey 3 bobbin jar is the premium choice for wholecloth, heirloom, and customer quilts where the back quality matters.
- How many bobbins come in a jar?
- Magna-Glide Delights jars typically contain 10–12 pre-wound bobbins. Check the current listing for the exact count.
- Are these compatible with all M-style longarm machines?
- Yes — Magna-Glide Delights M-size bobbins are compatible with all longarm machines using M-style bobbins.
- Is Cool Grey 3 (10CG3) the most popular grey bobbin?
- Yes — since 10CG3 is the top-selling grey Glide thread, the matching Cool Grey 3 bobbin jar is also the most popular grey bobbin option at Linda’s.
