I've been using the Juki now for about a week for piecing. It is AMAZING! Here's why I've fallen in love:
1. It's easy to see. Lots of space.
2. The stiches seem stronger than my other machine. I'm not sure how to explain this. They just seem more solid.
3. The automatic thread cutter plus the knee lift means that my focus is always on the fabric.
4. My piecing has been sooooo much more accurate! I'm sooooooooo happy. I have no idea if it is b/c of the machine or because I'm being more careful. But I am thrilled.
