## Questions & Answers

**Q: Where is this made?**
A: Made in the USA

**Q: Does the one side taper down so you can fold the paper back?**
A: This is the original add a quarter ruler.  They have now come out with add a quarter plus rulers.  They come in all the different sizes and they have the tapered edge to fold the paper back.  They cost a dollar or two more then this one.

**Q: What's the width?**
A: 2 inch

**Q: Do any of you paper piecing people regret not getting the 12 inch add a quarter plus ruler? Or are you happy with the 6 inch**
A: I do have both, but I think I probably used the 6 inch more than the 12 inch.  Think it depends on your block size.
