## Questions & Answers

**Q: Will the magnetic guide work on my machine?**
A: It works on any machine with a metal needle plate — most Brother, Singer, Janome, Husqvarna, Kenmore, and Babylock. If your needle or bobbin area is plastic, the magnet won't grip. The perforated ruler still works on its own

**Q: How small is the ruler, really?**
A: The ruler is 2.5" wide and 5.5" long — sized to sit under the presser foot, not to replace a quilting ruler. Great for setting seam widths and marking pivot points. Not a substitute for a 6" or 12" cutting ruler.

**Q: Is the magnet safe for my sewing machine?**
A: Yes. The magnet is designed to hold the guide in place, not to damage internal parts. When you're done, slide the guide off horizontally rather than pulling straight up.

**Q: Can I use it for 1/4" quilting seams?**
A: Absolutely — the 1/4" hole is one of the 16 perforations, and the 1/4" pivot point helps with binding corners. If your presser foot sits right over the 1/4" mark, try using the ruler to set the guide instead of directly under the foot.

**Q: What if I'm brand new to sewing?**
A: You're who we designed this for. The starter guide walks you through each step, and there are no complicated settings. Start with a 1/2" or 5/8" seam on scrap fabric — you'll feel the difference on your first straight line.
