Frequently Asked Questions
- What is the difference between an R-Point and a standard sharp?
- An R-Point (Regular Sharp) has a very slightly rounded tip compared to a true cutting sharp. This rounded point is ideal for woven quilting cottons — it pushes between fabric threads rather than cutting them, reducing the chance of skipped stitches and thread shredding.
- When should I use a size 18 needle vs. a size 16?
- Use a size 18 for thicker or denser fabrics, tightly woven backings, heavier thread (30wt or thicker), or when quilting through multiple dense batting layers. A size 16 is suitable for standard quilting cottons with 40wt thread.
- How often should I change my longarm needle?
- Most longarm quilters change needles every 8–10 hours of quilting time, or at the start of each new project. A dull needle causes skipped stitches, thread breakage, and fabric damage.
- Is the 134MR needle system compatible with my specific longarm machine?
- 134MR needles fit the vast majority of longarm and mid-arm quilting machines including APQS, Gammill, Handi Quilter, and Bernina Q-series machines. Always verify your machine’s needle system before ordering.
- Can I use longarm needles in a domestic sewing machine?
- No — 134MR longarm needles are designed for industrial and longarm machines. Domestic sewing machines use a different needle system (15x1 or 130/705H).
